  1. AIDS: acquired immunodeficiency syndrome

    Gilmore, N. J.; Beaulieu, R.; Steben, M.; Laverdière, M.

    2002-01-01

    Acquired immunodeficiency syndrome, or AIDS, is a new illness that occurs in previously healthy individuals. It is characterized by immunodeficiency, opportunistic infections and unusual malignant diseases. Life-threatening single or multiple infections with viruses, mycobacteria, fungi or protozoa are common. A rare neoplasm, Kaposi's sarcoma, has developed in approximately one third of patients with AIDS. More than 800 cases of AIDS have been reported in North America, over 24 of them in Ca...

  2. The Acquired Immunodeficiency Syndrome: current status.

    Quagliarello, V.

    1982-01-01

    A recently recognized syndrome of acquired immunodeficiency (Acquired Immunodeficiency Syndrome-AIDS) has arisen since June 1981. It has received international attention. The clinical spectrum consists of repeated opportunistic infections, rare malignancies, and autoimmune phenomena, occurring in previously healthy adults with no history of an immunologic disorder. The population subset at risk for this syndrome appears to be predominantly homosexual American males and intravenous drug abuser...

    Kaur, A; Rosenzweig, M; Johnson, R. P.

    2000-01-01

    Infection with the human immunodeficiency virus results in profound perturbations in immunological memory, ultimately resulting in increased susceptibility to opportunistic infections and acquired immunodeficiency syndrome (AIDS). We have used rhesus macaques infected with the simian immunodeficiency virus (SIV) as a model to understand better the effects of AIDS virus infection on immunological memory. Acute infection with SIV resulted in significant deficits in CD4+ helper responses to cyto...

    Molina Moguel, J L; Ruiz Illezcas, R; Forsbach Sánchez, S; Carreño Alvarez, S; Picco Díaz, I

    1990-12-01

    The object of this study was to determine how many of the patients treated at the Pediatric Odontology Clinic, a branch of the Maxillo-Facial Surgery Service at the Veinte de Noviembre Regional Hospital, ISSSTE, are VIH-positive of show serious manifestations of Acquired Immuno-Deficiency Syndrome (AIDS). For such purpose, 100 pediatric patients suffering from different systemic or local diseases were evaluated, the most common being hematological alterations. Results evidenced the presence of VIH in the blood of five of the pediatric subjects, all suffering from Hemophilia. PMID:2132469

  6. The acquired immunodeficiency syndrome in gay men.

    Jaffe, H W; Hardy, A M; Morgan, W M; Darrow, W W

    1985-11-01

    The acquired immunodeficiency syndrome (AIDS) is a major health problem for gay men in the United States. About three fourths of all reported cases have occurred in this population, and the number is projected to double in the next year. In Manhattan and San Francisco, AIDS is now the leading cause of premature mortality in men aged 25 to 44 years who have never married. In a sample of a cohort of gay men enrolled in a San Francisco clinic, 2.7% of the men had the syndrome and 26% had related conditions in 1984. Antibody to human T-lymphotropic virus, type III/lymphadenopathy-associated virus was found in sera from 67% of the men, including 58% of asymptomatic men. Behavioral factors associated with an increased risk of AIDS include large numbers of sexual partners, receptive anal intercourse, and "fisting." The adoption of safer lifestyles is currently the basis of attempts to control the syndrome in gay men. PMID:2996396

    2011-01-01

    Background Cytomegalovirus (CMV) retinitis is the most severe intraocular complication that results in total retinal destruction and loss of visual acuity in patients with acquired immunodeficiency syndrome (AIDS). This study aimed to investigate the fundus characteristics, systemic manifestations and therapeutic outcomes of CMV retinitis associated with AIDS.Methods It was a retrospective case series. CMV retinitis was present in 39 eyes (25 patients). Best corrected visual acuities, anterior segment, fundus features, fundus fluorescence angiography (FFA) and CD4+ T-lymphocyte counts of the patients with CMV retinitis associated with AIDS were analyzed. Intravitreal injections of ganciclovir (400 μg) were performed in 4 eyes (2 patients).Results Retinal vasculitis, dense, full-thickness, yellow-white lesions along vascular distribution with irregular granules at the border, and hemorrhage on the retinal surface were present in 28 eyes. The vitreous was clear or mildly opaque.Late stage of the retinopathy was demonstrated in 8 eyes characterized as atrophic retina, sclerotic and attenuated vessels, retinal pigment epithelium (RPE) atrophy, and optic nerve atrophy. Retinal detachment was found in 3 eyes. The average CD4+ T-lymphocyte count in peripheral blood of the patients with CMV retinitis was (30.6±25.3) ×106/L (range,(0-85) × 106/L). After intravitreal injections of ganciclovir, visual acuity was improved and fundus lesions regressed.Conclusions CMV retinitis is the most severe and the most common intraocular complication in patients with AIDS. For the patients with yellow-white retinal lesions, hemorrhage and retinal vasculitis without clear cause, human immunodeficiency virus (HIV) serology should be performed. Routine eye examination is also indicated in HIV positive patients.

  8. Cerebral involvement in acquired immunodeficiency syndrome (AIDS)

    Involvement of the central nervous system in acquired immune deficiency syndrome (AIDS) is usually due to opportunistic infections; these frequently offer a difficult differential diagnostic problem. Imaging methods play an important part in the elucidation of symptoms. CT and MR findings were analysed in 13 patients with AIDS and neurological symptoms. Some infections of the central nervous system (encephalitis of unknown aetiology, cytomegalic encephalitis, meningitis) may show cerebral atrophy or even no morphological changes. Toxoplasmosis and PML are the most common opportunistic infections typical changes on CT and MR may lead to diagnosis. MR offers advantages compared with CT in its higher sensitivity for the demonstration even of small lesions. (orig.)

  9. Improving Acquired Immunodeficiency Syndrome Related Cancer Outcomes through International Collaboration

    2011-01-01

    @@ The spectrum of cancers seen in human immunodeficiency virus (HIV)infected individuals is diverse and complex,and reflects an ever-changing HIV epidemic.In parts of the world where combination antiretroviral therapy (cART) is available,HIV-infected patients are living longer and are less likely to die of acquired immunodeficiency syndrome (AIDS)defining malignancies within a year or two of developing AIDS.

  10. Hemorrhagic abscess in a patient with the acquired immunodeficiency syndrome

    Cerebral toxoplasmosis is frequent among patients with the acquired immunodeficiency syndrome. The common computed tomography appearance of this complication is multiple low density area with ring enhancement. We describe a very rare picture of cerebral toxoplasmosis, this is multiple hemorrhagic toxoplasmic abscess. (orig.)

  11. Acquired immunodeficiency syndrome associated with blood-product transfusions

    Jett, J.R.; Kuritsky, J.N.; Katzmann, J.A.; Homburger, H.A.

    1983-11-01

    A 53-year-old white man had fever, malaise, and dyspnea on exertion. His chest roentgenogram was normal, but pulmonary function tests showed impaired diffusion capacity and a gallium scan showed marked uptake in the lungs. Results of an open-lung biopsy documented Pneumocystis carinii pneumonia. Immunologic test results were consistent with the acquired immunodeficiency syndrome. The patient denied having homosexual contact or using intravenous drugs. Twenty-nine months before the diagnosis of pneumocystis pneumonia was made, the patient had had 16 transfusions of whole blood, platelets, and fresh-frozen plasma during coronary artery bypass surgery at another medical center. This patient is not a member of any currently recognized high-risk group and is believed to have contracted the acquired immunodeficiency syndrome from blood and blood-product transfusions.

  13. Acquired immunodeficiency syndrome and its ocular complications

    Full Text Available Human immunodeficiency virus infection is the first major pandemic of the 20th century. At present, almost 10 million people are known to be infected with this virus, and it is estimated that by the year 2000, approximately 40 million people will be infected. Transmission of this deadly infection is predominantly by sexual contact. Individuals infected with this virus pass through several predictable stages with progressive decrease in circulating CD4+ T cells. During the advanced stage, these patients develop various opportunistic infections or malignancies, or both. It is this advanced stage that was first recognized as AIDS, which has a 100% mortality rate. The opportunistic organisms that can involve the eye in patients with AIDS include cytomegalovirus, herpes zoster, Toxoplasma gondii, Mycobacterium tuberculosis, Cryptococcus neoformans, Mycobacterium avium-intracellulare, Pneumocystis carinii, Histoplasma capsulatum, Candida, and others. Intraocular lesions from these agents often represent disseminated infections. Visual morbidity occurs secondary to retinitis due to cytomegalovirus, herpes zoster, or Toxoplasma gondii. Anti-viral agents such as ganciclovir or foscarnet are effective against cytomegalovirus infection. The role of the ophthalmologist in the diagnosis and management of AIDS is becoming increasingly important. Not only does the eye reflect systemic disease, but ocular involvement may often precede systemic manifestations. In the AIDS patient, the ophthalmologist thus has an opportunity to make not only a slight-saving, but also life-saving diagnosis of disseminated opportunistic infections.

  14. Cerebral computed tomography in men with acquired immunodeficiency syndrome

    Brun, B.; Boesen, F.; Gerstoft, J.; Nielsen, J.O.; Praestholm, J.

    Cerebral CT scannings were performed in 19 homosexual men with the acquired immunodeficiency syndrome (AIDS). Nearly half of them (9 patients) had cortical atrophy. Three patients with toxoplasmosis had cerebral pathology, in two of them with ring enhancement while the third had an ill-defined nonspecific lesion with slight heterogeneous enhancement without ring formation. Two patients with multifocal leucoencephalopathy and non-Hodgkin's lymphoma, respectively, presented non-enhancing, low attenuating lesions at CT.

    Acquired immunodeficiency syndrome (AIDS) remains ill-defined by lists of symptoms, infections, tumors, and disorders in metabolism and immunity. Low CD4 cell count, severe loss of body weight, pneumocystis pneumonia, and Kaposi's sarcoma are the major disease indicators. Lines of evidence indicate that patients living with AIDS have both immunodeficiency and autoimmunity. Immunodeficiency is attributed to deficits in the skin- and mucosa-defined innate immunity, CD4 T cells and regulatory T cells, presumably relating human immunodeficiency virus (HIV) infection. The autoimmunity in AIDS is evident by: (1) overproduction of autoantibodies, (2) impaired response of CD4 cells and CD8 cells, (3) failure of clinical trials of HIV vaccines, and (4) therapeutic benefits of immunosuppression following solid organ transplantation and bone marrow transplantation in patients at risk of AIDS. Autoantibodies are generated in response to antigens such as debris and molecules de novo released from dead cells, infectious agents, and catabolic events. Disturbances in metabolic homeostasis occur at the interface of immunodeficiency and autoimmunity in the development of AIDS. Optimal treatments favor therapeutics targeting on the regulation of metabolism to restore immune homeostasis. PMID:26676359

  17. Bronchogenic carcinoma in acquired immunodeficiency syndrome - report of two cases

    The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

  18. Management of Diabetes Mellitus in Patients with Acquired Immunodeficiency Syndrome

    Miulescu Rucsandra Dănciulescu

    2014-06-01

    Full Text Available Acquired immunodeficiency syndrome (AIDS is a human immune system disease characterized by increased susceptibility to opportunistic infections, certain cancers and neurological disorders. The syndrome is caused by the human immunodeficiency virus (HIV that is transmitted through blood or blood products, sexual contact or contaminated hypodermic needles. Antiretroviral treatment reduces the mortality and the morbidity of HIV infection but is increasingly reported to be associated with increasing reports of metabolic abnormalities. The prevalence and incidence of diabetes mellitus in patients on antiretroviral therapy is high. Recently, a joint panel of American Diabetes Association (ADA and European Association for the Study of Diabetes (EASD experts updated the treatment recommendations for type 2 diabetes (T2DM in a consensus statement which provides guidance to health care providers. The ADA and EASD consensus statement concur that intervention in T2DM should be early, intensive, and uncompromisingly focused on maintaining glycemic levels as close as possible to the nondiabetic range. Intensive glucose management has been shown to reduce microvascular complications of diabetes but no significant benefits on cardiovascular diseases. Patients with diabetes have a high risk for cardiovascular disease and the treatment of diabetes should emphasize reduction of the cardiovascular factors risk. The treatment of diabetes mellitus in AIDS patients often involves polypharmacy, which increases the risk of suboptimal adherence

  19. Cerebral toxoplasmosis and lymphoma in patients with Acquired Immunodeficiency Syndrome

    Toxoplasmosis now constitutes a relatively frequent central nervous system (CNS) complication of AIDS, primary CNS lymphoma being far less common. CT scanning using the double-dose delayed (D-D-D) scan technique has proved an effective way of helping in the diagnosis of these complications. 16 patients with CNS complications of the acquired immunodeficiency syndrome (AIDS) are described. All patients were male homosexuals. The most common demonstrable lesion in the parenchyma was toxoplasmosis, which produced an area of focal oedema, usually containing a central zone of nodular or ring-shaped enhancement. Cerebral atrophy was also a common finding. One patient had diffuse peri-ventricular lymphomatous infiltration, and a further two patients had both cerebral toxoplasmosis and lymphoma. A delayed double dose contrast examination appears to be the most accurate method of outlining the total extent of CNS disease in these patients. 11 refs., 7 figs., 2 tabs

  20. Brain CT in pediatric patients with acquired immunodeficiency syndrome

    Review of the cranial Ct scans of 28 infants and children with acquired immunodeficiency syndrome revealed that cerebral atrophy was the most common finding, occurring in 19 patients. Next most common was basal ganglionic calcification, present in 11 patients without the usual biochemical abnormalities associated with this finding. In ten patients varying degrees of abnormally low attenuation were seen in the white matter. In contrast to the situation in adults, there were no examples of mass lesions due to opportunistic infections. Pathologic specimens were available in eight patients. These confirmed the presence of calcific vasculopathy in four patients with basal ganglionic calcification on CT and showed calcification in an additional four patients. Other findings included glial nodules, tract degeneration, and white matter pallor

  1. Human immunodeficiency virus and acquired immunodeficiency syndrome: correlation but not causation.

    Duesberg, P H

    1989-01-01

    AIDS is an acquired immunodeficiency syndrome defined by a severe depletion of T cells and over 20 conventional degenerative and neoplastic diseases. In the U.S. and Europe, AIDS correlates to 95% with risk factors, such as about 8 years of promiscuous male homosexuality, intravenous drug use, or hemophilia. Since AIDS also correlates with antibody to a retrovirus, confirmed in about 40% of American cases, it has been hypothesized that this virus causes AIDS by killing T cells. Consequently, ...

  2. Radionuclide brain imaging in acquired immunodeficiency syndrome (AIDS)

    Infection with the Human Immunodeficiency Virus type 1 (HIV-1) may produce a variety of central nervous system (CNS) symptoms and signs. CNS involvement in patients with the Acquired Immunodeficiency Syndrome (AIDS) includes AIDS dementia complex or HIV-1 associated cognitive/motor complex (widely known as HIV encephalopathy), progressive multifocal leucoencephalopathy (PML), opportunistic infections such as Toxoplasma gondii, TB, Cryptococcus and infiltration by non-Hodgkin's B cell lymphoma. High resolution structural imaging investigations, either X-ray Computed Tomography (CT scan) or Magnetic Resonance Imaging (MRI) have contributed to the understanding and definition of cerebral damage caused by HIV encephalopathy. Atrophy and mainly high signal scattered white matter abnormalities are commonly seen with MRI. PML produces focal white matter high signal abnormalities due to multiple foci of demyelination. However, using structural imaging techniques there are no reliable parameters to distinguish focal lesions due to opportunistic infection (Toxoplasma gondii abscess) from neoplasm (lymphoma infiltration). It is studied the use of radionuclide brain imaging techniques in the investigation of HIV infected patients. Brain perfusion Single Photon Emission Tomography (SPET), neuroreceptor and Positron Emission Tomography (PET) studies are reviewed. Greater emphasis is put on the potential of some radiopharmaceuticals, considered to be brain tumour markers, to distinguish intracerebral lymphoma infiltration from Toxoplasma infection. SPET with 201Tl using quantification (tumour to non-tumour radioactivity ratios) appears a very promising technique to identify intracerebral lymphoma

  4. An Increased Risk of Osteoporosis during Acquired Immunodeficiency Syndrome

    2004-08-01

    Full Text Available Osteoporosis is characterized by decreased bone mineral density and mechanistic imbalances of bone tissue that may result in reduced skeletal strength and an enhanced susceptibility to fractures. Osteoporosis in its most common form affects the elderly (both sexes and all racial groups of human beings. Multiple environmental risk factors like acquired immune deficiency syndrome (AIDS are believed to be one of the causes of osteoporosis. Recently a high incidence of osteoporosis has been observed in human immunodeficiency virus (HIV infected individuals. The etiology of this occurrence in HIV infections is controversial. This problem seems to be more frequent in patients receiving potent antiretroviral therapy. In AIDS, the main suggested risk factors for the development of osteoporosis are use of protease inhibitors, longer duration of HIV infection, lower body weight before antiretroviral therapy, high viral load. Variations in serum parameters like osteocalcin, c-telopeptide, levels of elements like Calcium, Magnesium, Phosphorus, concentration of vitamin-D metabolites, lactate levels, bicarbonate concentrations, amount of alkaline phosphatase are demonstrated in the course of development of osteoporosis. OPG/RANKL/RANK system is final mediator of bone remodeling. Bone mineral density (BMD test is of added value to assess the risk of osteoporosis in patients infected with AIDS. The biochemical markers also aid in this assessment. Clinical management mostly follows the lines of treatment of osteoporosis and osteopenia.

  5. Computed tomography of the lungs in acquired immunodeficiency syndrome

    Computed tomography of the chest was performed on 42 occasions as part of the diagnostic work-up in 26 homosexual men with, or suspected of the acquired immunodeficiency syndrome (AIDS). In 17 cases both the chest radiographs and the lung scans were abnormal, and bronchoscopy and/or lung biopsy established an etiologic diagnosis in the majority of these cases. In 9 cases CT of the lungs revealed unequivocal interstitial infiltration in the presence of a normal chest radiography, and subsequently and etiologic agent was demonstrated in all these cases. In 9 cases, patients with symptoms indicative of pulmonary infection had both a normal chest radiograph and a normal lung scan, and in none of these cases did the clinical course or additional diagnostic procedures indicate the presence of current opportunistic lung infection. CT of the lungs seems to identify accurately those patients with severe HIV-related diseases in whom invasive diagnostic procedures such as bronchoalveolar lavage and/or lung biopsy should be done.

    There are several reports of Fanconi syndrome (FS) with or without nephrogenic diabetes insipidus (NDI) in patients with human immunodeficiency virus (HIV) infection, treated with various antiretroviral medications like cidofovir, adefovir, didenosine and tenofovir. But neither FS nor NDI has been documented with abacavir therapy. We are reporting the first case of abacavir-induced reversible FS with NDI in a patient with acquired immunodeficiency syndrome, who recovered completely with suppo...

  11. Kaposi sarcoma and lymphadenopathy syndrome: limitations of abdominal CT in acquired immunodeficiency syndrome

    Moon, K.L. Jr.; Federle, M.P.; Abrams, D.I.; Volberding, P.; Lewis, B.J.

    1984-02-01

    Abdominal computed tomography (CT) was performed in 31 patients with Kaposi sarcoma (KS) related to acquired immunodeficiency syndrome (AIDS), three patients with classic KS, and 12 patients with the newly described lymphadenopathy syndrome (LNS). The frequency, distribution, and appearance of lymphadenopathy and splenomegaly were similar in the AIDS-related KS and LNS groups. Rectal and perirectal disease was identified in 86% of homosexual men studied; rectal KS could not be distinguished from proctitis on CT criteria alone. No CT abnormalities were seen in patients with classic KS. The CT demonstration of retroperitoneal, mesenteric, or pelvic adenopathy or of rectal or perirectal disease in patients with AIDS-related KS is not necessarily indicative of widespread involvement with the disease.

After clinical examination and investigations, she was diagnosed with disseminated tuberculosis (including central nervous system involvement, and Human immunodeficiency virus/acquired immune deficiency syndrome. Her hospital stay was complicated. She developed stridor and a cerebrovascular accident with left hemiplegia. She died approximately 2 weeks after admission. The potential causes of her stridor included a mediastinal mass or a central mechanism secondary to tuberculosis meningitis. Limited resources precluded definitive imaging of the chest to rule out a mediastinal mass. Further, an autopsy was not done. Despite these limitations, this case is unique because it reports the presence of both stridor and tuberculosis meningitis in an adult patient.Keywords: Human immunodeficiency virus, acquired immune deficiency syndrome, meningitis, stridor, tuberculosis

    We report a case of nontropical pyomyositis in a patient with acquired immunodeficiency syndrome and disseminated Mycobacterium avium infection, in which severe myalgia was the presenting symptom over several weeks. Multifocal muscle lesions were identified by gallium scanning and magnetic resonance imaging techniques. The epidemiology, possible pathogenesis, clinical features, diagnostic imaging, and therapy are reviewed. Early suspicion of nontropical pyomyositis in severely immunocompromised patients with cryptic myalgia is recommended

    We report a patient with acquired immunodeficiency syndrome dementia complex (ADC) that presented human immunodeficiency virus infection as an initial manifestation. A 34-year-old man developed disturbance of consciousness and severe abulia over 3 months. The CD4 lymphocyte count was 7.9/microl, while human immunodeficiency virus RNA in blood amounted to 4.2 x 10(4) copies/ml. T2-weighted magnetic resonance imaging showed diffusely high signal intensity in the deep white matter of both cerebral hemispheres. On the 20th hospital day, the patient died of sepsis caused by methicillin-resistant Staphylococcus aureus. Autopsy findings in the brain included increased glial cells and multinucleated giant cells in cerebral white matter and subcortical gray matter. These features were compatible with ADC.

    2002-02-01

    Full Text Available The association of Reiter's Syndrome (RS with the Acquired Immunodeficiency Syndrome (AIDS is seldom mentioned in the medical literature. This report illustrates this relationship in a 46 years old male patient suffering from AIDS (CD4+ = 240 cells/mm³, CD8+ = 1,301 cells/mm³ and viral load = 330,000 copies/ml, pulmonary tuberculosis (positive catarrhal bacilluscopy, and RS. The diagnosis of RS was based on the combination of dermatological and articular alterations. The patient's cutaneous lesions were characterized by exfoliation and the formation of crusts located on the face, scalp, genitals, hands, and feet; onychodystrophy with opacity; yellowish coloring; and hyperkeratosis of the nails. Articular lesions led to progressive deformity of phalangeal joints of the hands, and intensive arthralgia, mainly of the larger joints (shoulders, elbows, hips and knees. AIDS treatment was administered with anti-retroviral drugs (zidovudine and didanosine; for tuberculosis (isoniazid, rifampicine, and pyrazinamide; and (prednisone and inometacine for the RS. The patient recovered with the improvement of articular symptoms; however, on the eighth day of treatment, the patient showed significant hemoptysis and hypovolemic shock, and died. The association of RS and HIV infection is reviewed.

  1. Optimising technetium 99m diethylenetriaminepenta-acetate lung clearance in patients with the acquired immunodeficiency syndrome

    Pneumocystis carinii pneumonia (PCP) has become a major cause of morbidity and mortality due to infectious diseases, largely as a result of the acquired immunodeficiency syndrome (AIDS) epidemic. Since the mortality from recurrent infection is between 40% and 60%, early diagnosis and therapy are the keys to survival. The role of technetium 99m diethylenetriaminepentacetate (DTPA) aerosol pulmonary clearance was studied in 81 patients with AIDS. The mathematical technique of curve stripping was found to be the optimal method of analysis and to provide an overall sensitivity of 94% for the detection of interstitial pneumonitis. The procedure was superior to standard pathology parameters and radiography and more convenient than gallium 67 scintigraphy. (orig.)

  2. Radiological findings in three acquired immunodeficiency syndrome patients with Rhodococcus equi pneumonia

    Objective: To study the imaging appearances of Rhodococcus equi pneumonia in three patients with acquired immunodeficiency syndrome ( AIDS). Methods: Thoracic imaging appearances of' Rhodococcus equi pneumonia in three patients with AIDS were retrospectively analyzed. Results: The chest radiograph showed patchy consolidations and small nodules (n=3), large consolidations with multiple cavitations (n=2). CT showed large lobar or segmental consolidations with multiple cavitations (n=2), patchy consolidations (n=2), bronchiectasis (n=1), multiple small centrilobular nodules (n=2) and tree-in-bud patterns (n=2). Conclusion: The most common radiological findings in AIDS patients with Rhodococcus equi pulmonary infection are large consolidations with multiple cavitations and multiple centrilobular nodules.

    2012-01-01

    Pancreatic tuberculosis (TB) is a relatively rare disease that can mimic carcinoma,lymphoma,cystic neoplasia,retroperitoneal tumors,pancreatitis or pseudocysts.Here,I report the case of a 31-year-old immigrant Burmese woman who exhibited epigastralgia,fever,weight loss and an epigastric mass.The patient was diagnosed with pancreatic TB and acquired immunodeficiency syndrome,and was treated with antituberculous drugs and percutaneous catheter drainage without a laparotomy.The clinical presentation,radiographic investigation and management of pancreatic TB are summarized in this paper to emphasize the importance of considering this rare disease in the differential diagnosis of pancreatic masses concomitant with human immunodeficiency virus infection.I also emphasize the need for both histopathological and microbiological diagnosis via fineneedle aspiration.

  5. Unsuspected pulmonary alveolar proteinosis in a patient with acquired immunodeficiency syndrome: a case report

    Niazi Masooma

    2011-02-01

    Full Text Available Abstract Introduction Diffuse lung infiltrates are a common finding in patients with acquired immunodeficiency syndrome and causes range from infectious processes to malignancies or interstitial lung diseases. Pulmonary alveolar proteinosis is a rare pulmonary disorder rarely reported in patients infected with human immunodeficiency virus. Secondary pulmonary alveolar proteinosis is associated with conditions involving functional impairment or reduced numbers of alveolar macrophages. It can be caused by hematologic malignancies, inhalation of toxic dust, fumes or gases, infectious or pharmacologic immunosuppression, or lysinuric protein intolerance. Case presentation A 42-year-old African American man infected with human immunodeficiency virus was admitted with chronic respiratory symptoms and diffuse pulmonary infiltrates. Chest computed tomography revealed bilateral spontaneous pneumothoraces, for which he required bilateral chest tubes. Initial laboratory investigations did not reveal any contributory conditions. Histological examination of a lung biopsy taken during video-assisted thoracoscopy showed pulmonary alveolar proteinosis concurrent with cytomegalovirus pneumonitis. After ganciclovir treatment, our patient showed radiologic and clinical improvement. Conclusion The differential diagnosis for patients with immunosuppression and lung infiltrates requires extensive investigations. As pulmonary alveolar proteinosis is rare, the diagnosis can be easily missed. Our case highlights the importance of invasive investigations and histology in the management of patients infected with human immunodeficiency virus and pulmonary disease who do not respond to empiric therapy.

    Human immunodeficiency virus (HIV) infection is associated with increased intestinal translocation of microbial products and enteropathy as well as alterations in gut bacterial communities. However, whether the enteric virome contributes to this infection and resulting immunodeficiency remains unknown. We characterized the enteric virome and bacterial microbiome in a cohort of Ugandan patients, including HIV-uninfected or HIV-infected subjects and those either treated with anti-retroviral therapy (ART) or untreated. Low peripheral CD4 T cell counts were associated with an expansion of enteric adenovirus sequences and this increase was independent of ART treatment. Additionally, the enteric bacterial microbiome of patients with lower CD4 T counts exhibited reduced phylogenetic diversity and richness with specific bacteria showing differential abundance, including increases in Enterobacteriaceae, which have been associated with inflammation. Thus, immunodeficiency in progressive HIV infection is associated with alterations in the enteric virome and bacterial microbiome, which may contribute to AIDS-associated enteropathy and disease progression.

  7. Nonspecific interstitial pneumonitis: a common cause of pulmonary disease in the acquired immunodeficiency syndrome

    During a 4.4-year period, nonspecific interstitial pneumonitis was seen in 41 of 110 (38%) patients with the acquired immunodeficiency syndrome and accounted for 32% (48/152) of all episodes of clinical pneumonitis. Diffuse alveolar damage was typically a feature of nonspecific interstitial pneumonitis, but neither lung biopsy nor bronchoalveolar lavage detected a pathogen. Of these 41 patients, 13 had no associated pulmonary tumor and had not been exposed to pulmonary toxins, whereas 28 patients had either concurrent pulmonary Kaposi sarcoma, previous experimental therapies, or a history of pneumocystis pneumonia or drug abuse. Of these 41, 23 had normal chest radiographs. The clinical features of patients with nonspecific interstitial pneumonitis were similar to those of patients with pneumocystis pneumonia, although histologic findings showed less severe alveolar damage in patients with nonspecific interstitial pneumonitis (p less than 0.001). Pathologic evaluation and clinical follow-up suggest that many clinical episodes of pneumonitis in patients with the acquired immunodeficiency syndrome are due to nonspecific interstitial pneumonitis of unknown cause

  8. The human immunodeficiency virus preventive vaccine research at the French National Agency for acquired immunodeficiency syndrome research

    Elizabeth Fischer

    2005-02-01

    Full Text Available The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS epidemic is of unprecedented gravity and is spreading rapidly, notably in the most disadvantaged regions of the world. The search for a preventive vaccine is thus an absolute priority. For over 10 years the French National Agency for AIDS research (ANRS has been committed to an original program combining basic science and clinical research. The HIV preventive vaccine research program run by the ANRS covers upstream research for the definition of immunogens, animal models, and clinical research to evaluate candidate vaccines. Most researchers in 2004 believe that it should be possible to obtain partial vaccine protection through the induction of a strong and multiepitopic cellular response. Since 1992, the ANRS has set up 15 phases I and II clinical trials in order to evaluate the safety and the capacity of the candidate vaccines for inducing cellular immune responses. The tested candidate vaccines were increasingly complex recombinant canarypox viruses (Alvac containing sequences coding for certain viral proteins, utilized alone or combined with other immunogens (whole or truncated envelope proteins. ANRS has also been developing an original strategy based on the utilization of lipopeptides. These comprise synthetic fragments of viral proteins associated with lipids that facilitate the induction of a cellular immune response. These approaches promptly allowed the assessment of a prime-boost strategy combining a viral vector and lipopeptides.

    2012-06-01

    Full Text Available Acquired Immunodeficiency Syndrome (AIDS, a global disease, caused by the Human Immunodeficiency Virus (HIV is arguably the greatest health problem of this age and there is need to make first class information on the management of HIV/AIDS available through the use of Web-Based Technology. This paper examined the various ways of contacting HIV and the effort made by Information and Technology to make life easier for people living with the virus in Nigeria. Questionnaires were distributed to Doctors and people living with HIV/AIDS to access their knowledge and belief about the said disease. MySQL was used to generate the database, to store all the vital information about the patients, their Doctors and their complaints. PHP programming for the implementation of the interfaces, Dreamweaver HTML for the design of the web-based application, T-test and Microsoft Excel were used for the analysis of data collected. The study looked into the occupation, age range and the marital status of different categories of people living with the virus. It was discovered that there were quite large numbers of people who are living with the virus.

  10. Immune reconstitution inflammatory syndrome in a patient with cryptococcal lymphadenitis as the first presentation of acquired immunodeficiency syndrome

    Tahir M

    2007-01-01

    Full Text Available Immune reconstitution inflammatory syndrome is commonly seen in acquired immunodeficiency syndrome (AIDS patients having concomitant opportunistic infection, following initiation of highly active anti-retroviral therapy (HAART. We describe IRIS in a young man with unknown human immunodeficiency virus (HIV status who presented with cryptococcal lymphadenitis as the first manifestation of AIDS. At presentation the patient had features overlapping with tuberculosis (TB lymphadenitis which was ruled out by fine needle aspiration cytology. The patient responded to antifungal treatment but following the start of HAART, symptoms recurred which were managed conservatively. Though TB is common in India, a thorough workup including histopathology of lymph node should be done before the patient is started on anti-tuberculosis treatment. HIV infected patients having opportunistic co-infection should be closely monitored following initiation of HAART.

  13. Bone paracoccidioidomycosis associated with acquired immunodeficiency syndrome: evaluation by radiological methods - a case report

    Paracoccidioidomycosis is a chronic granulomatous disease, caused by the Paracoccidioides brasiliensis fungus. This disease involves primarily the lungs, although disseminated forms may occur. Bone involvement is rare, and is associated to systemic disease or may present as a focal lesion. An association between paracoccidioidomycosis and the acquired immunodeficiency syndrome (AIDS) was first established in 1989. There are only a few reports on this association, and none of them was the fungus isolated from bone lesions. This is the first case report on the paracoccidioidomycosis-AIDS association in which bone lesions demonstrated infection by P. brasiliensis. The authors propose the inclusion of paracoccidioidomycosis in the differential diagnosis of lytic bone lesions in patients with AIDS and discuss the role of radiological diagnostic in this case.

  14. 99mTc-ECD brain SPECT imaging in patients with acquired immunodeficiency syndromes

    In order to investigate the changes of regional cerebral blood flow (rCBF) in patients with acquired immunodeficiency syndromes (AIDS), 99mTc-ECD brain SPECT imaging was performed in 5 patients with AIDS and 16 sex and age matched normal controls, and the rCBF percentages compared to the cerebellum were calculated using a semi-quantitative processing software. Hypo-perfusions in the right and left frontal, temporal, parietal lobe, basal ganglia and left thalamus were seen in 1 patient with dementia. Hypo-perfusions in the right and left frontal and temporal lobe were seen in 4 asymptomatic patients. The rCBF in the right and left frontal, temporal, parietal lobe, basal ganglia and thalamus, front and pons were decreased significantly in patients with AIDS than those of the control subjects (p < 0.005). It is concluded that there exists reduced cortico-subcortical rCBF in AIDS patients

  15. Toxoplasmosis of spinal cord in acquired immunodeficiency syndrome patient presenting as paraparesis: A rare entity

    Sachin R Agrawal

    2014-01-01

    Full Text Available Although brain has been the most common site for toxoplasma infection in acquired immunodeficiency syndrome patients, involvement of spinal cord by toxoplasma has been rarely found. Spinal cord toxoplasmosis can present as acute onset weakness in both lower limbs associated with sensory and bladder dysfunction. A presumptive diagnosis can be made in patients with CD4 count <100/mm 3 based on a positive serum Toxoplasma gondii IgG antibodies, no recent prophylaxis against toxoplasmosis, intramedullary ring enhancing lesion in spinal cord supported by similar lesions in brain parenchyma. Institutions of antitoxoplasma treatment in such patients result in prompt clinical response and therefore avoiding the need of unnecessary invasive diagnostic tests. Here, we report a case of toxoplasmic myelitis in immunocompromised patient presenting as myelopathy who showed significant clinical improvement after starting antitoxoplasma treatment. Hence toxoplasmic myelitis should be considered in toxoplasma seropositive immunocompromised patients presenting as myelopathy and imaging studies showing ring enhancing intramedullary lesion.

  16. Gallium-67 scans of the chest in patients with acquired immunodeficiency syndrome

    Eighty-six [67Ga]citrate chest scans were performed in 71 adult patients with the acquired immunodeficiency syndrome. Forty-five of these patients also had Kaposi's sarcoma. Only 29 of 57 abnormal scans were correlated with abnormal chest radiographs. Chest radiographs were negative for 27 scans and unavailable for one. Several scan patterns were seen. Diffusely increased lung uptake was seen most commonly with Pneumocystis carinii pneumonia, but also other infections and noninfectious inflammatory conditions. Focal uptake corresponding to regional lymph node groups occurred most often with Mycobacterium avium-intracellulare but aslo with lymphoma. Localized intrapulmonary uptake was seen in bacterial pneumonias. Perihilar activity occurred in two cases. When chest radiographs were abnormal and 67Ga scans negative, the most common diagnosis was pulmonary Kaposi's sarcoma

  17. Human papillomavirus-associated cancers as acquired immunodeficiency syndrome defining illnesses

    Shohreh Shahabi

    2013-04-01

    Full Text Available The Centers for Disease Control currently report cervical, vulvar, vaginal, anal and some head and neck cancers as human papillomavirus (HPV-associated cancers. Only cervical cancer is listed amongst acquired immunodeficiency syndrome (AIDS defining illnesses. All of these cancers may represent progression of the immunocompromised state with the inability to eradicate viral infection. This study reports the case of a 27-year old HIV positive female presenting with a persistent right vulvar exophytic lesion. High-risk HPV analysis and immunostaining for P16 were both positive. A biopsy of the lesion revealed invasive squamous cell carcinoma. The patient underwent neoadjuvant radiation and chemotherapy followed by a radical vulvectomy. During treatment, her CD4 T-lymphocyte count decreased to 120 advancing her condition from HIV to AIDS. This case suggests that all HPV-associated cancers should be included as AIDS defining illnesses.

  19. Study of opportunistic intestinal parasitic infections in human immunodeficiency virus/acquired immunodeficiency syndrome patients

    Manish Kumar Mathur

    2013-01-01

    Full Text Available Introduction: Intestinal parasites predominantly coccidian parasites are a common cause for diarrhea in human immunodeficiency virus (HIV-positive patients. Materials and Methods: The study was conducted during January 2009-December 2010. A total of 1,088 stool samples from 544 seropositive HIV positive cases were examined microscopically for ova and cyst using wet mount preparations and stained smears. Out of 544 patients, 343 had prolonged diarrhea for more than 4 weeks, 57 had acute diarrhea of lesser than 7 days and 144 were asymptomatic cases who attended out-patient department; included in this study after taking consent from patients. Enteric pathogens were detected in 274 (50.36% of the 544 patients. Results and Conclusions: The parasites identified were Cryptosporidium (135, Isospora belli (42, Cyclospora (12, Microsporidia (02, Entamoeba histolytica (49, Hookworm (34. Intestinal parasites in chronic diarrhea were significantly higher than the acute diarrhea (63.05% vs. 7.35%; P < 0.05. Parasitic pathogens were frequently associated with HIV-positive patients with diarrhea in Western India. Stools of all HIV-positive patients with diarrhea should thoroughly be investigated to identify etiologic agents for proper management.

  1. Kaposi sarcoma of the conjunctiva and eyelids associated with the acquired immunodeficiency syndrome

    Three studies were performed to assess more accurately the prevalence, natural history, and appropriate treatment of acquired immunodeficiency syndrome (AIDS)-related Kaposi sarcoma involving ocular structures. The first study was a prospective examination of 100 male homosexuals with AIDS-related Kaposi sarcoma for signs of ophthalmic involvement. Of the 20 patients who had ophthalmic lesions, 16 had eyelid lesions and seven had conjunctival lesions. In four patients, the ophthalmic lesion was the first, and initially the only, clinically identified manifestation of Kaposi sarcoma. The second study was a retrospective review of all patients with ophthalmic Kaposi sarcoma examined at one institution over a six-year period to determine its natural history and response to therapy. Most lesions were slowly progressive and responded to systemic drug therapy. Six patients were successfully treated with radiation therapy to prevent complications. The third study was a retrospective review of all patients with AIDS-related ophthalmic Kaposi sarcoma treated with local irradiation by one radiation oncologist. Each of 12 patients showed a response to treatment, and ten had a complete resolution of lesions, but recurrences were common. Side effects included skin erythema in six patients and hair loss in one patient. For local treatment of ophthalmic Kaposi sarcoma, irradiation appears to be safe and effective for palliative therapy

  2. Computed tomography of the lungs in acquired immunodeficiency syndrome. An early indicator of interstitial pneumonia

    Hartelius, H.; Gaub, J.; Jensen, L.I.; Jensen, J.; Faber, V.

    Computed tomography of the chest was performed on 42 occasions as part of the diagnostic work-up in 26 homosexual men with, or suspected of the acquired immunodeficiency syndrome (AIDS). In 17 cases both the chest radiographs and the lung scans were abnormal, and bronchoscopy and/or lung biopsy established an etiologic diagnosis in the majority of these cases. In 9 cases CT of the lungs revealed unequivocal interstitial infiltration in the presence of a normal chest radiography, and subsequently and etiologic agent was demonstrated in all these cases. In 9 cases, patients with symptoms indicative of pulmonary infection had both a normal chest radiograph and a normal lung scan, and in none of these cases did the clinical course or additional diagnostic procedures indicate the presence of current opportunistic lung infection. CT of the lungs seems to identify accurately those patients with severe HIV-related diseases in whom invasive diagnostic procedures such as bronchoalveolar lavage and/or lung biopsy should be done.

  3. Anterior segment manifestations of human immunodeficiency virus/acquired immune deficiency syndrome

    Biswas Jyotirmay

    2008-01-01

    Full Text Available Ocular complications are known to occur as a result of human immunodeficiency virus (HIV disease. They can be severe leading to ocular morbidity and visual handicap. Cytomegalovirus (CMV retinitis is the commonest ocular opportunistic infection seen in acquired immune deficiency syndrome (AIDS. Though posterior segment lesions can be more vision-threatening, there are varied anterior segment manifestations which can also lead to ocular morbidity and more so can affect the quality of life of a HIV-positive person. Effective antiretroviral therapy and improved prophylaxis and treatment of opportunistic infections have led to an increase in the survival of an individual afflicted with AIDS. This in turn has led to an increase in the prevalence of anterior segment and adnexal disorders. Common lesions include relatively benign conditions such as blepharitis and dry eye, to infections such as herpes zoster ophthalmicus and molluscum contagiosum and malignancies such as squamous cell carcinoma and Kaposi′s sarcoma. With the advent of highly active antiretroviral therapy, a new phenomenon known as immune recovery uveitis which presents with increased inflammation, has been noted to be on the rise. Several drugs used in the management of AIDS such as nevirapine or indinavir can themselves lead to severe inflammation in the anterior segment and adnexa of the eye. This article is a comprehensive update of the important anterior segment and adnexal manifestations in HIV-positive patients with special reference to their prevalence in the Indian population.

  4. Infection and T lymphocyte subpopulations: changes associated with bacteremia and the acquired immunodeficiency syndrome.

    Fishman, J A; Martell, K M; Rubin, R H

    1983-01-01

    Patients with bacteremia, bacterial endocarditis, or acquired immunodeficiency syndrome (AIDS) were prospectively studied using monoclonal antibody reagents to assess alterations in T-lymphocyte subpopulations. Patients with endocarditis had significantly higher ratios of T-helper (OKT4+) to T-suppressor-cytotoxic (OKT8+) cells than did patients with bacteremia alone. Staphylococcus aureus endocarditis patients had a mean ratio of 8.49 (range 4.73-22.36) while S aureus bacteremia had a mean ratio of 2.75 (range 2.15 to 3.21). Similar results were found with Staphylococcus epidermidis endocarditis (mean 1.62) and bacteremia (mean 1.23). Klebsiella pneumoniae endocarditis (5.10) and sepsis (4.32), and E coli bacteremia (2.15). Nine male patients with AIDS had markedly depressed ratios (mean 0.25, range 0.04 to 0.67) while eight male homosexuals with unexplained lymphadenopathy ("pre-AIDS") had normal or increased ratios. Bacteremic infections are associated with an increased OKT4+/OKT8+ ratio with the degree of increase dependent upon virulence, location, and duration of infection. The immunomodulating effects of infection are manifested in changes in T-cell subsets, and these measurements can be useful in clinical management. PMID:6094086

  5. Erythrovirus B19 infection in acquired immunodeficiency syndrome: screening by histopathology, immunohistochemistry, and in situ hybridization

    Sérgio Setúbal

    2006-06-01

    Full Text Available Erythrovirus B19 infects erythrocytic progenitors, transiently interrupting erythropoiesis. In AIDS patients it causes chronic anemia amenable to treatment. We looked for evidences of B19 infection in stored bone marrow material from patients with acquired immunodeficiency syndrome. Histological sections were made from stored paraffin blocks from 33 autopsies (39 blocks and 35 biopsies (45 blocks, 30 patients performed from 1988 to 2002. They were examined after hematoxylin-eosin (HE staining, immunohistochemical (IHC, and in situ hybridization. HE revealed intra-nuclear inclusion bodies ("lantern cells" suggesting B19 infection in 19 sections corresponding to 19 of 63 patients examined with this test. Seven of 78 sections subjected to immunohistochemistry were positive, corresponding to 7 of 58 patients examined with this test. Fourteen sections corresponding to 13 of the 20 HE and/or IHC positive patients were subjected to in situ hybridization, with six positives results. Among the 13 patients subjected to the three techniques, only one gave unequivocal positive results in all and was considered a true positive. The frequency of B19 infection (1/63 patients in the material examined can be deemed low.

  6. Respiratory failure in patients with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia.

    Maxfield, R A; Sorkin, I B; Fazzini, E P; Rapoport, D M; Stenson, W M; Goldring, R M

    1986-05-01

    Seven patients with acquired immunodeficiency syndrome (AIDS) and Pneumocystis carinii pneumonia were studied to define the pathophysiology of their respiratory failure. The patients had fever, cough, dyspnea, hypoxemia, and diffuse infiltrates on chest x-ray. Biopsies revealed a spectrum of alveolar filling, interstitial edema and infiltration, and fibrosis. The patients were studied on mechanical ventilation to assess the effect of positive end-expiratory pressure (PEEP) and supplemental oxygen on shunt fraction. Mean anatomic shunt (measured on 100% oxygen) was 34 +/- 8%, which increased significantly (p less than .001) to 43 +/- 9% when the FIO2 was decreased to 40% to 60% (physiologic shunt), indicating ventilation/perfusion (V/Q) imbalance or impaired diffusion. Increasing PEEP by 9 +/- 2 cm H2O reduced the anatomic shunt to 30 +/- 7% (p less than .01) and the physiologic shunt to 37 +/- 7% (p less than .02). There was a similar decrease in anatomic and physiologic shunts in five studies, a greater decrease in physiologic shunt in four, and a greater decrease in anatomic shunt in two. Evidence of alveolar recruitment with PEEP, measured by an increase in static thoracic compliance, was found in only one study. There was no correlation between the effect of PEEP on compliance and its effect on shunt. The data suggest that in patients with AIDS and P. carinii pneumonia, PEEP can decrease shunt by reducing the anatomic shunt, improving V/Q imbalance, and converting areas of anatomic shunt to areas of low V/Q. P. carinii pneumonia in patients with AIDS can produce a clinical and pathophysiologic pattern similar to that described in the adult respiratory distress syndrome. PMID:3516574

    We present the case of a boy with acquired immunodeficiency syndrome (AIDS) in whom ultrasound revealed the presence of a calculous cholecystitis. Abdominal ultrasound was essential in the initial diagnosis and the assessment of the response to treatment. This entity has rarely been reported in the pediatric radiology literature. In our patient, the cholecystitis may have been caused by infection, and the involvement of regional lymphatic obstruction in the pathogenesis is considered. (Author) 14 refs

    The prevalence of lymphoma in primary immunodeficiency cases and autoimmune diseases, as well as on a background of immunodeficiency following organ transplants, is increasing. The lymphoma treatment success rate is known to be a low prognosis. Our study aimed to emphasize the low survival rates in immunodeficient vs. immunocompetent lymphoma patients and also to investigate the effect of rituximab in patients with ataxia telangiectasia and other immunodeficiencies. We summarized the clinical characteristics and treatment results of 17 cases with primary immunodeficiency that developed non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) retrospectively. Seven patients were diagnosed with ataxia-telangiectasia, two with common variable immunodeficiency, two with selective IgA deficiency, one with X-related lymphoproliferative syndrome, one with Wiskott-Aldrich syndrome, one with Epstein-Barr virus-related lymphoproliferative syndrome, one with interleukin-2-inducible T-cell kinase (ITK) deficiency, and one with lymphoma developing after autoimmune lymphoproliferative syndrome (ALPS). One patient underwent a renal transplant. Of the nine males and eight females (aged 3-12 years, median = 7) that developed lymphoma, seven were diagnosed with HL and ten with NHL (seven B-cell, three T-cell). The NHL patients were started on the Berlin-Frankfurt-Münster, POG9317, LMB-96, or R-CHOP treatment protocols with reduced chemotherapy dosages. HL cases were started on the doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and/or cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) protocol, also with modified dosages. Importantly, all seven cases of HL are alive and in remission, while six of the ten NHL patients have died. Primary immunodeficiency is a strong predisposing factor for developing lymphoma. Low treatment success rates relative to other lymphomas and difficulties encountered during treatment indicate that new treatment agents are needed

  10. Acquired immunodeficiency syndrome-associated cancers in Sub-Saharan Africa.

    Thomas, J O

    2001-04-01

    Sub-Saharan Africa is considered home to more than 60% of all human immunodeficiency virus (HIV) infected cases, with an estimated adult prevalence of 8.0%. It is stated that this region has contributed more than 90% of childhood deaths related to HIV infection and about 93% of childhood acquired immunodeficiency syndrome (AIDS)-related deaths. Although no country in Africa is spared of the infection, the bulk is seen in East and South Africa, with the highest recorded rates of 20% to 50% in Zimbabwe. On the other hand, West Africa is less affected, while countries in Central Africa have relatively stable infection rates. Although infections, especially tuberculosis, have emerged as the most important HIV/AIDS-associated killers in recent times, AIDS-associated malignancies are increasingly identified in the late stages. As a result of incomplete data from African countries, it is unclear whether the epidemiology and risks of these cancers are the same as observed in the developed countries. Since the advent of AIDS, epidemic Kaposi's sarcoma (KS) has become more common in both sexes in Africa, with a dramatic lowering of the male to female ratio from 19:1 to 1.7:1, especially in East Africa. Although there has been a rising trend of AIDS-associated non-Hodgkin's lymphoma (NHL) worldwide, there is an apparently lower risk in Africa compared with that in the developing world. At present, there is no strong evidence linking increased incidence of invasive cervical cancer to the HIV epidemic; however, some studies have demonstrated an association between HIV and the increased prevalence of human papilloma virus (HPV) and cervical intraepithelial neoplasia (CIN). On the other hand, HIV infection is now established as a risk factor for the development of squamous cell neoplasia of the conjunctiva based on studies from Rwanda, Malawi, and Uganda. Despite the problems and limitations of information from sub-Saharan Africa, interesting trends of HIV/AIDS-related cancers

No clinical study has related serum selenium concentration to skin diseases in human immunodeficiency virus (HIV/acquired immunodeficiency syndrome (AIDS patients. Methods: In this study, 134 newly diagnosed HIV patients that satisfied the inclusion criteria were included. Skin diseases were clinically diagnosed and fasting venous blood was taken for assessment of serum selenium using an atomic absorption spectrophotometer. Results: The mean age of HIV subjects with and without skin disease were not significantly different: 32.72 ± 9.21 versus 35.86 ± 8.55 years, P = 0.077, respectively. The mean of serum selenium (0.51 ± 0.48 versus 0.81 ± 0.39, CD4+ count (228.06 ± 212.89 versus 446.41 ± 182.87, and body mass index (BMI; 21.09 ± 3.58 versus 23.53 ± 3.35 were significantly lower (P 0.05. Conclusion: serum selenium concentration was lower among HIV subjects with skin diseases than those without skin disease. Pruritic papular eruption, xeroderma

  12. Acquired immunodeficiency syndrome-related primary cerebral lymphoma: response to irradiation

    Acquired immunodeficiency syndrome-related primary cerebral lymphoma (AIDS-PCL) is uncommon. Fourteen cases of presumed AIDS-PCL between 1986 and 1995 were reviewed retrospectively in order to characterize the natural history, and the response to radiotherapy. The median age was 38 years (range 24-65). The median interval between seropositive diagnosis of HIV and AIDS-PCL was 28 months (range 5-113). The median duration of symptoms was 2 weeks (range 0.2-12). At presentation, the Eastern Cooperative Oncology Group performance status (PS) was PS1 (2/14 patients), PS2 (6/14) and PS3 (6/14). The symptoms and signs were non-specific and depended on the site and extent of cerebral involvement. There was no characteristic pattern of brain imaging in terms of size, number, location or pattern of contrast enhancement of the cerebral lesions. Nine patients received various fractionation-dose schedules (range 8-50 Gy). Complete and partial responses were seen in 2/9 and 3/9 cases, respectively. Clinical stabilization of neurological symptoms was noted in 3/9 cases and disease progression in 1/9. The median survival times (MST) from presentation for irradiated and non-irradiated patients were 9.3 and 2.1 weeks, respectively (range 0.9-43.1). Although patient selection introduced bias, there appears to be a modest improvement in MST for treated patients. The MST with radiotherapy alone remains poor, but radiotherapy may provide palliation. For some selected patients, a prolonged response is possible. Copyright (1999) Blackwell Science Pty Ltd

    Human immunodeficiency virus (HIV) infection associated aneurysmal vasculopathy is a rare complication of HIV infection affecting the pediatric and adult population. We present a case of a 7-year-old male child known to have a congenitally acquired HIV infection presenting with a ruptured left distal internal carotid artery fusiform aneurysm that was diagnosed on MRI scans 6 months prior to his presentation. He underwent craniotomy and successful aneurysm reconstruction. He had uncomplicated ...

  14. Production of acquired immunodeficiency syndrome-associated retrovirus in human and nonhuman cells transfected with an infectious molecular clone

    The authors considered an infectious molecular clone of acquired immunodeficiency syndrome-associated retrovirus. Upon transfection, this clone directed the production of infectious virus particles in a wide variety of cells in addition to human T4 cells. The progeny, infectious virions, were synthesized in mouse, mink, monkey, and several human non-T cell lines, indicating the absence of any intracellular obstacle to viral RNA or protein production or assembly. During the course of these studies, a human colon carcinoma cell line, exquisitely sensitive to DNA transfection, was identified

  15. Recursion-based depletion of human immunodeficiency virus-specific naive CD4(+) T cells may facilitate persistent viral replication and chronic viraemia leading to acquired immunodeficiency syndrome.

    Tsukamoto, Tetsuo; Yamamoto, Hiroyuki; Okada, Seiji; Matano, Tetsuro

    2016-09-01

    Although antiretroviral therapy has made human immunodeficiency virus (HIV) infection a controllable disease, it is still unclear how viral replication persists in untreated patients and causes CD4(+) T-cell depletion leading to acquired immunodeficiency syndrome (AIDS) in several years. Theorists tried to explain it with the diversity threshold theory in which accumulated mutations in the HIV genome make the virus so diverse that the immune system will no longer be able to recognize all the variants and fail to control the viraemia. Although the theory could apply to a number of cases, macaque AIDS models using simian immunodeficiency virus (SIV) have shown that failed viral control at the set point is not always associated with T-cell escape mutations. Moreover, even monkeys without a protective major histocompatibility complex (MHC) allele can contain replication of a super infected SIV following immunization with a live-attenuated SIV vaccine, while those animals are not capable of fighting primary SIV infection. Here we propose a recursion-based virus-specific naive CD4(+) T-cell depletion hypothesis through thinking on what may happen in individuals experiencing primary immunodeficiency virus infection. This could explain the mechanism for impairment of virus-specific immune response in the course of HIV infection. PMID:27515208

  16. Toxoplasma encephalitis in Haitian adults with acquired immunodeficiency syndrome: a clinical-pathologic-CT correlation

    The clinical data, histologic findings, and computed tomographic (CT) abnormalities in eight adult Haitians with toxoplasma encephalitis were analyzed retrospectively. Diagnosis was established by identification of Toxoplasma gondii on autopsy in five and brain biopsy in three specimens and subsequently confirmed by the immunoperoxidase method. All these patiens, six of whom had been in the United States for 24 months or less, had severe idiopathic immunodeficiency syndrome. All were lymphopenic and six were on treatment for tuberculosis when the toxoplasma encephalitis developed. All patients were studied with CT when they developed an altered mental status and fever associated with seizures and/or focal neurologic deficits. Scans before treatment showed multiple intraparenchymal lesions in seven and a single lesion in the thalamus in one. Ring and/or nodular enhancement of the lesions was found in six and hypodense areas in two. Progressions of abnormalities occurred on serial studies. These CT findings that were best shown on axial and coronal thin-section double-dose contrast studies were useful but not diagnostically pathognomonic. In patients with similar clinical presentation CT is recommended to identify focal areas of involvement and to guide brain biopsy or excision so that prompt medical thereapy of this often lethal infection can be instituted

  17. A preliminary report of 99Tcm-ECD brain SPECT imaging in patients with acquired immunodeficiency syndrome

    Objective: To investigate the changes of regional cerebral blood flow (rCBF) in patients with acquired immunodeficiency syndrome (AIDS). Methods: 99Tcm-ECD brain SPECT imaging was performed on 5 patients with AIDS and 16 sex- and age-matched normal controls. The rCBF percentages compared to the cerebellum were calculated using a semi-quantitative processing software. Results: Hypo-perfusions in the right and left frontal, temporal, parietal lobe, basal ganglia and left thalamus were seen in 1 patient with dementia. Hypo-perfusions in the right and left frontal and temporal lobe were seen in 4 patients without dementia. The rCBF in the right and left frontal, temporal, parietal lobe, basal ganglia and thalamus, straight gyri and pons decreased significantly in patients with AIDS than those of the control subjects (P < 0.01). Conclusion: There is reduced cortico-subcortical rCBF in patients with AIDS

    The objective was to study changes in the occurrence of human immunodeficiency virus type 1-related Kaposi's sarcoma and the association with degree of immunodeficiency over time. Danish patients with acquired immunodeficiency syndrome (AIDS) diagnosed between 1979 and 1990 (n = 687) were followed...... developing Kaposi's sarcoma after the AIDS diagnosis. Age, antiretroviral therapy, and primary Pneumocystis carinii pneumonia prophylaxis failed to influence the development of Kaposi's sarcoma. Thus, the occurrence of Kaposi's sarcoma remained constant over time but developed later in the course of AIDS and...

  20. Behaviors Influencing Human Immunodeficiency Virus Transmission in the Context of Positive Prevention among People Living with HIV/Acquired Immunodeficiency Syndrome in Iran: A Qualitative Study

    Seyed Ramin Radfar

    2014-01-01

    Full Text Available Background: Identifying factors, which influence health behaviors is critical to designing appropriate and effective preventive programs. Human immunodeficiency virus (HIV transmission is highly related to people behaviors and understanding factors influencing healthy behaviors among Iranian people living with HIVs (PLHIVs/acquired immunodeficiency syndrome (AIDS is very important to tailor an effective response to HIV/AIDS epidemic. Methods: This study was conducted as a qualitative study by methods of focus group discussion and in-depth interview in six provinces of Iran with 64 PLHIVs to determine factors influence engagement in positive prevention. Results: Knowledge and education, feelings of responsibility and positive prevention practices were identified as the primary domains of engagement. These domains were found to be influenced by feelings of ostracism and frustration, poverty, barriers to disclosure of HIV status, access to and utilization of drug abuse treatment services and antiretroviral therapy, adherence to treatment, age, religiousness, sex work, singleness, and incarceration. Conclusions: Designing new interventions and updating current interventions directed toward the aforementioned factors should be addressed by responsible Iranian authorities in order to have a national effective response on the HIV/AIDS epidemic.

  1. Is human immunodeficiency virus/acquired immunodeficiency syndrome decreasing among Brazilian injection drug users? Recent findings and how to interpret them

    Francisco I Bastos

    2005-02-01

    Full Text Available We briefly review findings from Brazilian settings where the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS epidemic among injection drug users (IDUs seems to be decreasing, highlighting recent findings from Rio de Janeiro and discussing methodological alternatives. Former analyses using serologic testing algorithm for recent HIV seroconversion have shown that HIV incidence has been low in IDUs recruited by two different surveys carried out in Rio, where low injection frequencies and infection rates have been found among new injectors. The proportion of AIDS cases among IDUs in Rio has been fairly modest, compared to São Paulo and especially to the southernmost states. Notwithstanding, the interpretation of findings from serial surveys constitutes a challenge, magnified in the assessment of HIV spread among IDUs due to the dynamic nature of the drug scenes and limitations of sampling strategies targeting hard-to-reach populations. Assessment of epidemic trends may profit from the triangulation of data, but cannot avert biases associated with sampling errors. Efforts should be made to triangulate data from different sources, besides exploring specific studies from different perspectives. In an attempt to further assess the observed trends, we carried out original analyses using data from Brazilian AIDS databank.

  2. Risky sexual behavior related to human immunodeficiency virus/acquired immunodeficiency syndrome among seasonal labor migrants: A cross-sectional study from far Western Region of Nepal

    Dillee Prasad Paudel

    2013-01-01

    Full Text Available Background: Human immunodeficiency virus/acquired immunodeficiency syndrome is a global public health problem; enormously affecting the national economy, social development and human rights with posing a challenge to human civilization. Seasonal labor migrants are the most at risk population for HIV/AIDS and their risky sexual behaviors exacerbate its transmission. The aim of the study was to explore the HIV/AIDS related sexual behavior of migrant workers. Materials and Methods: A cross-sectional study was carried out among 372 migrant workers backing to Nepal from Banbasa border of India-Nepal during August-October 2010. Migrants having permanent residents of far western region, Nepal were individually contacted at the entry point of Nepal and interviewed in a confidential environment after obtaining informed consent. Data were analysed using the SPSS (16.0 version. Descriptive and inferencial statistics were applied considering P 3 sex partners. Most (82.25% had vaginal sex and 43.54% reported the consistent use of condom. About 64.76% had sex after drinking alcohol. Age, education, monthly income and nature of works were significant with risky behaviors. Conclusion: Inconsistent condom use, multiple sexual partners and sex after drinking alcohol have a cumulative effect on the risk of HIV transmission.

  3. MR findings of central nervous system involvement in acquired immunodeficiency syndrome patient : a report of two cases

    Central nervous system (CNS) manifestations in acquired immunodeficiency syndrome (AIDS) patients are an early and common feature. The spectrum of AIDS-related CNS diseases are encephalitis caused by the human immunodeficiency virus(HIV) itself, opportunistic infection, infarct and malignancy. We experienced two cases of CNS involvement in AIDS and they were serologically diagnosed as HIV encephalitis and CNS toxoplasmosis, respectively. In the case of the HIV encephalitis patient, brain MRI showed a non-enhancing lesion with high signal intensity on T2WI and low signal on T1WI and there was no mass effect on the right frontal lobe, periventricular white matter, splenium of the corpus callosum or bilateral basal ganglia. In the other case of CNS toxoplasmosis, MR showed multiple nodular and rim enhanced mass lesions in the right basal ganglia, thalamus and periventricular white matter, which were of low signal intensity on T1WI and of high intensity on T2WI. We thus report the related MRI findings

    Carlos Alberto Blanco Córdova

    2015-02-01

    Full Text Available The Herpes Zoster is produced by the reactivation of the Chicken Pox Zoster Virus. It has an incidence of three cases for each thousand inhabitants a year, and they increase the possibility to suffer it with the age. A 48 year old case of a patient with atypical Zoster with postherpetic neuralgia who came to the Dermatology consultation with cutaneous and mucous lesions is presented. This article has the objective to describe the evolution of the Herpes Zoster in the last patient diagnosed like seropositive to the virus of Human Immunodeficiency Virus It is considered of concern once both entities association was given, indicator that although Herpes Zoster incidence is low, considering the possible presence of diseases that involve the immune system. We conclude that in the presence of the clinical variety of Atypical Herpes Zoster, the coexistence of other diseases that compromise the immune system, as the Human Immunodeficiency Virus must be considered.

    Here the authors discuss evidence in human and animal models supporting two opposing views regarding the pathogenesis of human immunodeficiency virus (HIV) in the central nervous system (CNS): (1) HIV infection in the CNS is a compartmentalized infection, with the virus-infected macrophages entering the CNS early, infecting resident microglia and astrocytes, and achieving a state of latency with evolution toward a fulminant CNS infection late in the course of disease; or alternatively, (2) ev...

  6. Food Security in Households of People Living With Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome: A Cross-sectional Study in a Subdivision of Darjeeling District, West Bengal

    2016-01-01

    Objectives: Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) adversely impacts food security in households of people living with HIV/AIDS (PLWHA). Little research has focused on food insecurity among PLWHA in India. The purpose of this study was to identify the prevalence of and factors relating to food security in households of PLWHA in the Siliguri subdivision of Darjeeling, West Bengal, India. Methods: A cross-sectional community-based study was carried out among 173 PLWHA residing in Siliguri and registered at the Anti-retroviral Therapy Centre of North Bengal Medical College & Hospital. Data was collected at the household level with interviews of PLWHA using a food security survey instrument. We analyzed the associations using logistic regression. Results: The prevalence of household food security among the participants was 50.9% (88/173). Five years or more of schooling, higher socioeconomic class and males were found to be significantly associated with a higher likelihood of food security. A later stage of the disease and the presence of other family members with HIV/AIDS were significantly associated with a lower likelihood of food security. The major coping strategies to deal with food insecurity in the acute phase HIV infection included borrowing money (56.1%), followed by spousal support, loans from microfinance institutions, banks, or money lenders, borrowing food, or selling agricultural products. Conclusions: The present study revealed that only about half of households with PLWHA were food secure. Prior interventions relating to periods of food and economic crisis as well as strategies for sustaining food security and economic status are needed in this area. PMID:27499166

    Kaposi's sarcoma is frequently found in association with acquired immunodeficiency syndrome (AIDS). We report on radiotherapy for patients with AIDS-related Kaposi's sarcoma at Tokyo Metropolitan Komagome Hospital. Between April 1991 and May 1997, radiotherapy was given to 11 lesions in eight men with AIDS-related Kaposi's sarcoma to relieve their symptoms. The lesions involved the head and neck region, the legs, and the gastrointestinal tract. Radiotherapy was carried out with 4-MV photon through parallel opposed field or high energy electrons. Total doses ranged from 20 to 38 Gy, with a median of 30 Gy, delivered in 2- to 3-Gy fractions. Four patients were given other treatments prior to the radiotherapy. Acute reaction was evaluated according to the modified acute radiation morbidity scoring criteria of the Radiation Therapy Oncology Group (RTOG). Radiotherapy had relieved the symptoms in all patients at completion of this therapy. Lesions that involved the hard palate and vocal cords had completely disappeared. The lesions that received radiotherapy were controlled without symptoms until the patients died. Patients who had the head and neck region treated exhibited severe acute mucosal reaction (at a dose of 30 Gy, there was grade 2 morbidity by modified RTOG criteria, in two patients, and grade 3 in three patients) although the radiation therapy was completed for these patients. Radiotherapy promises a favorable outcome for symptom relief in AIDS-related Kaposi's sarcoma. (author)

    Purpose: The imaging characteristics of cryptococcosis in rheumatoid arthritis (RA) patients were analyzed by comparing them with those of acquired immunodeficiency syndrome (AIDS) and immunocompetent patients, and the imaging findings were correlated with pathological findings. Methods: Two radiologists retrospectively compared the computed tomographic (CT) findings of 35 episodes of pulmonary cryptococcosis in 31 patients with 3 kinds of underlying states (10 RA, 12 AIDS, 13 immunocompetent), focusing on the nature, number, and distribution of lesions. The pathological findings of 18 patients (8 RA, 2 AIDS, 8 immunocompetent) were analyzed by two pathologists, and then correlated with imaging findings. Results: The frequencies of consolidation and ground glass attenuation (GGA) were significantly higher, and the frequency of peripheral distribution was significantly lower in the RA group than in the immunocompetent group. Peripheral distribution was less common and generalized distribution was more frequent in the RA group than in the AIDS group. The pathological findings of the AIDS and immunocompetent groups reflected their immune status: There was lack of a granuloma reaction in the AIDS group, and a complete granuloma reaction in the immunocompetent group, while the findings of the RA group varied, including a complete granuloma reaction, a loose granuloma reaction and a hyper-immune reaction. Cases with the last two pathologic findings were symptomatic and showed generalized or central distribution on CT. Conclusion: Cryptococcosis in the RA group showed characteristic radiological and pathological findings compared with the other 2 groups.

    To better define the role of environmental factors on LDL phenotypic expression, the authors determined LDL patterns in patients with acquired immunodeficiency syndrome (AIDS), and infection characterized by hypertriglyceridemia and weight loss. Similar to previous studies, plasma triglyceride levels were increased, whereas plasma cholesterol, LDL cholesterol, and HDL cholesterol levels were decreased in the AIDS subjects compared to those in age-matched controls. The percentage of AIDS subjects with the LDL B phenotype was increased 2.5-fold, demonstrating an increased prevalence of the LDL B phenotype in an acquired form of hypertriglyceridemia. For each LDL phenotype in AIDS, serum triglyceride levels were higher than the same phenotypic pattern in controls, with the most marked elevations in triglycerides found in AIDS subjects with the LDL B phenotype. In contrast to what was observed in controls, HDL cholesterol levels were decreased in all AIDS subjects and were unrelated to LDL pattern. Total and LDL cholesterol levels were higher in controls with the LDL B phenotype than in those with the LDL A phenotype, but there was no difference in total and LDL cholesterol in AIDS subjects with LDL B compared to A. On multiple regression analysis in subjects with AIDS, plasma triglyceride levels, age, and HDL cholesterol all contribute to the occurrence of the LDL B phenotype, but elevations in plasma triglyceride levels are the strongest independent predictor. Body mass index was not a predictor of LDL B phenotype in AIDS. These results suggest that disturbances in triglyceride metabolism that are caused by AIDS lead to the appearance of the LDL subclass B phenotype and provide further evidence that environmental or disease states that perturb lipid metabolism can produce an increased prevalence of the LDL B phenotype. 35 refs., 1 fig., 5 tabs.

  11. Magnetic resonance imaging: early detection of central nervous system involvement in acquired immunodeficiency syndrome (AIDS)

    Central Nervous System (CNS) involvement, whether primary by the Human Immunodeficiency Virus - HIV - itself, or secondary (toxoplasmosis or lymphoma) is remarkably frequent in AIDS, in 40 to 70% of cases, depending upon the author. In order to study the natural history of this illness, a cohort of 25 asymptomatic seropositive patients have been established. Every 6 months these patients undergo biological and clinical examinations, as well as Magnetic Resonance brain scans. After two examinations at a 6 month's interval, the first results are reported. Out of these 25 cases, 9 present anomalies: One patient with diffuse cerebral atrophy and 8 others with high signal intensity areas on T2 weighted sequences, like those of the Multiple Sclerosis. No relationship could be demonstrated between the existence of these lesions and various criteria such as age, sex, risk factors and T4 cells count. The nature of these lesions is not lear. They certainly indicate early involvement of the CNS after primary infection by the HIV virus. They may either represent scars of the primary infection or early alterations announcing developing encephalopathy

    1985-01-01

    We studied whether volunteers giving blood to the Greater New York Blood Program (GNYBP) cooperated with procedures implementing public health recommendations intended to decrease the risk of acquired immunodeficiency syndrome (AIDS) transmission by blood transfusion. Predonation medical screening was expanded to exclude donors who might be ill with AIDS. To exclude possible asymptomatic carriers of the disease, members of groups at increased risk of AIDS were asked either not to give blood or to give it for laboratory studies. A confidential questionnaire, administered to all donors after medical screening, provided the vehicle for donors to advise the GNYBP whether their donation was for laboratory studies or for patient transfusion. We found that the number of male donors decreased; AIDS-related questions in medical history led to a 2 percent increase in donor rejections; 97 percent of donors said their blood could be used for transfusions; 1.4 percent said their blood could be used for laboratory studies only; and 1.6 percent did not respond. Only units designated for transfusion were released to hospitals. People who indicated that their donation was for laboratory studies had a higher prevalence of markers for hepatitis B virus and of antibodies to cytomegalovirus. White cell counts and helper/suppressor T lymphocyte ratios were not significantly different in the two groups. We conclude that volunteer donors have cooperated with the established procedures. None of the laboratory assays identified blood units donated by individuals who, based on information about AIDS high-risk groups, designated their donation for laboratory studies. PMID:3969698

  15. X-ray and CT findings of soft tissue and bone infections secondary to acquired immunodeficiency syndrome

    Objective: To summarize X-ray and CT findings of soft tissue and bone infections secondary to acquired immunodeficiency syndrome (AIDS). Methods: The data of X-ray and CT findings of soft tissue and bone infections in 18 patients with AIDS were retrospectively collected and analyzed. Results: Of 18 patients with AIDS, the CT features of soft tissue demonstrated that subcutaneous patchy high density in 1 case which considered as cellulitis, round low density lesions with ring enhancement in 6 cases which considered as soft tissue abscesses, heterogeneous density lesions with peripheral enhancement in 1 case which considered as pyomyositis. Of 18 patients with AIDS, septic arthritis was found in 4 cases involving knee lesion in 3 cases and hip lesion. In the 4 case, the X-ray films showed bony destruction in 2 cases and the CT showed bone destruction in 3 cases and arthroedema in 4 cases. Of 18 patients with AIDS, osteomyelitis was found in 9 cases of which tuberculosis was considered in. 8 cases and vertebral involvement in 6 cases. In the 9 cases, the X-ray films and CT displayed bony destruction, hyperostosis, small sequestra, and intervertebral space narrowing. Of 18 patients with AIDS, costal lesions were found in 3 cases in which the CT showed expandable bony destruction. Of 18 patients with AIDS, ilium and sacroiliac joint lesions were found in 1 case in which the X-ray films and CT showed bony destruction, sequestra, and joint widening. Of 18 patients with AIDS, chronic pyogenic osteomyelitis of femur was found in 1 case in which the X-ray films showed bony destruction, hyperostosis osteosclerosis, and periosteal reaction. Conclusion: The X-ray and CT features of soft tissue and bone infections secondary to AIDS are characterized. The X-ray and CT are useful tools to early diagnose soft tissue and bone infections secondary to AIDS. (authors)

    The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

    Paracoccidioidomycosis is a chronic granulomatous disease, caused by the Paracoccidioides brasiliensis fungus. This disease involves primarily the lungs, although disseminated forms may occur. Bone involvement is rare, and is associated to systemic disease or may present as a focal lesion. An association between paracoccidioidomycosis and the acquired immunodeficiency syndrome (AIDS) was first established in 1989. There are only a few reports on this association, and none of them was the fungus isolated from bone lesions. This is the first case report on the paracoccidioidomycosis-AIDS association in which bone lesions demonstrated infection by P. brasiliensis. The authors propose the inclusion of paracoccidioidomycosis in the differential diagnosis of lytic bone lesions in patients with AIDS and discuss the role of radiological diagnostic in this case.

    Objective: To study the chest radiographic appearances of the non-tuberculous mycobacterial (NTM) pulmonary infection in patients with acquired immune deficiency syndrome (AIDS). Methods: Ten patients with AIDS and NTM underwent chest X-ray radiography and 7 patients performed high-resolution CT (HRCT) scan. Chest radiographic features of' NTM in patients with AIDS were retrospectively analyzed. Results: The chest radiograph showed bilateral pulmonary involvement in 6 cases and single lung involvement in 4 cases (3 cases in the right, 1 case in the left). Patchy air space consolidation (6 cases), large consolidation (5 cases), cavitation (5 cases), small nodules (3 cases), military nodules (2 cases), linear opacity (1 cases) were demonstrated on radiography. On HRCT, air space consolidation (7 cases), small nodules (6 cases), large consolidation (5 cases) with cavitation and cylindric bronchiectasis after the absorption of consolidation, enlarged hilar and mediastinal lymph nodes (4 cases), ground-glass opacities (3 cases), military nodules and 'tree-in-bud' sign (2 case), pleural effusion (1 case), pericardial effusion (1 case) and fibrotic band (1 case) were found. Conclusion: The most common radiographic appearances of NTM in patients with AIDS are bilateral small nodules, large consolidation with cavitation and cylindric bronchiectasis, enlarged hilar and mediastinal lymph nodes.

  1. Primary testicular non-Hodgkin's lymphoma with atrial mass as an initial presentation of acquired immunodeficiency syndrome

    The association between human immunodeficiency virus (HIV) infection and the increased incidence of testicular tumors is a recent well-organized phenomenon. Testicular tumors in the setting of HIV infection are most frequently of germ cell origin, less commonly lymphomas. We are presenting a unique case of testicular non-Hodgkin's B-cell lymphoma with associated atrial mass and mediastinal lymphadenopathy. The patient was not known to be HIV positive at the time of presentation. The initial clinical, radiological and gross pathologic impression was that of seminoma. Discussion of the differential diagnosis and appropriate work up is presented. (author)

  2. Effect of traditional Chinese medicine for treating human immunodeficiency virus infections and acquired immune deficiency syndrome: Boosting immune and alleviating symptoms.

    To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

    2015-01-01

    Full Text Available Background: Illness uncertainty is a source of a chronic and pervasive psychological stress for people living with human immunodeficiency virus (HIV/acquired immune deficiency syndrome (AIDS (PLWH, and largely affects their quality of life and the ability to cope with the disease. Based on the uncertainty in illness theory, the social support is one of the illness uncertainty antecedents, and influences the level of uncertainty perceived by patients. Aim: To examine uncertainty in PLWH and its correlation with social support in Iran. Materials and Methods: This cross-sectional correlational study was conducted with 80 PLWH presenting to AIDS Research Center, Tehran, Iran in 2013. The data collected using illness uncertainty and social support inventories were analyzed through Pearson′s correlation coefficient, Spearman′s correlation coefficient, and regression analysis. Results: The results showed a high level of illness uncertainty in PLWH and a negative significant correlation between perceived social support and illness uncertainty ( P = 0.01, r = -0.29. Conclusion: Uncertainty is a serious aspect of illness experience in Iranian PLWH. Providing adequate, structured information to patients as well as opportunities to discuss their concerns with other PLWH and receive emotional support from their health care providers may be worthwhile.

    1996-01-01

    This report presents systematic clinical data regarding psychiatric diagnoses, personal and family psychiatric histories, and symptomatologic aspects of 90 consecutive human immunodeficiency virus (HIV)-seropositive and acquired immune deficiency syndrome (AIDS) patients, of whom slightly less than two thirds were at risk due to intravenous drug abuse. In addition, a comparison was made between the distribution patterns of these variables at various stages of HIV illness and related at-risk behaviors. Eighty-four percent of the patients met criteria for a spectrum of DSM-III-R diagnoses (mostly affective) that were associated with high rates of affective and alcohol abuse disorders among first-degree relatives. Mood disorders did not differ significantly between the two main groups at risk (intravenous drug users [IVDUs] v others) by gender, age, or stage of illness. The overall data from the rating scales show high levels of psychic and somatic anxiety in the early stages of illness, whereas cognitive symptoms, retardation, and disorientation are dominant in later stages. A noteworthy finding in this study is that many depressed patients demonstrated current and/or past hypomanic, hyperthymic, or cyclothymic features with no evidence of brain damage detectable by computed axial tomography (CAT). These temperamental attributes, which preceded HIV infection, may have served as risk factors for both drug abuse and impulsive sexual behavior in all types of at-risk groups. PMID:8826691

  8. Identical rearranged forms of JC polyomavirus transcriptional control region in plasma and cerebrospinal fluid of acquired immunodeficiency syndrome patients with progressive multifocal leukoencephalopathy.

    2003-10-01

    Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease of the central nervous system (CNS) caused by the human polyomavirus JC (JCV). JCV has a hypervariable noncoding transcriptional control region (TCR) that spans the origin of replication of the JCV genome through to the first ATG start codon for late gene transcription. The archetype form of TCR is frequently found in the urine and kidneys of healthy and immunocompromised subjects. However the rearranged forms, whose prototype is Mad-1, possibly generated by deletion and duplication of segments of the archetype sequence, are found in the brain and cerebrospinal fluid (CSF) of PML patients. In this study the authors compared JCV TCR detected in paired CSF, plasma, and urine samples of 11 acquired immunodeficiency syndrome (AIDS) patients affected by PML to try to determine where the rearranged JCV TCRs are selected. In one patient, it was also possible to amplify and sequence the TCR in the brain and lymphocytes. Moreover, in 5/11 patients, the CSF, plasma, and urine samples corresponding to 2 months after PML development were available; and in another patient, it was possible to sequence the TCR in plasma and lymphocytes sampled 8 months before the onset of PML. The presence of the same TCR sequences in all the CSF and plasma samples taken from individual patients could strengthen the hypothesis that the blood is a compartment where JCV may replicate and undergo rearrangement of the TCR. This further supports the hypothesis that JCV reaches the brain by a hematogenous route and indicates that the JCV TCR sequences detected in plasma could be used as an early marker of JCV pathogenicity before the clinical appearance of PML in immunocompromised patients.

  9. Neuroradiology of acquired immunodeficiency syndrome

    This paper discusses MRI and CT scanning in the evaluation of AIDS patients with neurological symptoms. MRI is the more sensitive of the two techniques but has poor tissue specificity. Contrast enhancement and identification of tissue calcification on CT scans may improve tissue characterization, but a specific etiological diagnosis may not be possible with either MRI or CT scanning; confirmation by biopsy or the response to treatment is often needed. The finding of multiple focal cerebral lesions on MRI and CT scans usually indicates T. gondii infection. Toxoplasmosis may, however, coexist with primary CNS lymphoma or with fungal, mycobacterial, or viral infection. The presence of a solitary focal cerebral lesion, especially on MRI scans, suggests lymphoma or infection with an agent other than T. gondii. Focal cerebral lesions show a variety of complex signal patterns on MRI and enhancement patterns on CT, none of which are specific for a single etiology. Focal lesions on MRI and CT scans are usually associated with focal neurological deficits, but a significant minority of these lesions, especially those seen on MRI scans, may cause only generalized complaints, such as headache and encephalopathy. MRI and CT are both useful for monitoring therapy and show a reduction in the size, number, and enhancement of lesions with successful treatment. The authors conclude that, owing to its greater sensitivity, MRI appears to be more useful for detecting recurrent disease

    @@ Acquired von Willebrand syndrome (AvWS) is kind of bleeding disorder with laboratory findings similar to those in congenital yon Willebrand disease (vWD).AvWS doesn's have any personal or family history of bleeding, but is associated with certain diseases or abnormal conditions or drugs. Although AvWS is being stated as a rare disease, it has gained more and more attention during the past years. Not because of the severity of the disease, but it is more common than we thought and most patients don' t have a proper diagnosis.

    We present the main findings observed on the high-resolution computed tomography examinations of 15 patients with acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia. The high-resolution computed tomography and autopsy findings of 5 patients were also compared. The most frequently observed high-resolution computed tomography patterns were ground-glass attenuation, consolidation areas, crazy-paving pattern and cysts. Nodules and intralobular reticulation were less frequently observed. Ground-glass attenuation and consolidation areas corresponded to alveolar filling with inflammatory exudate. Thickening of the interlobular septa was due to cell infiltration and edema. One patient presented interlobular reticulation, and the pathology study revealed alveolar septa thickening due to cell infiltration and fibrosis. Nodules observed in one of the patients corresponded to a patchy intra alveolar accumulation of microorganisms and inflammatory cells forming a 'granulomatous' pattern. (author)

  15. Knowledge, attitudes and practices regarding human immunodeficiency virus/acquired immune deficiency syndrome and sexually transmitted infections among health care providers in Lahore, Pakistan

    Human Immunodeficiency Virus (HIV) infection is a global problem of extraordinary dimensions and has so far resulted in nearly 25 million deaths worldwide. Health care providers (HCPs) are considered to play a pivotal role in the provision of preventive and curative services to individuals suffering from HIV/AIDS and sexually transmitted infections. Pakistan, which was previously categorised as having a low-prevalence, high-risk HIV epidemic, is now facing a concentrated HIV epidemic among its most at-risk populations such as injecting drug users. The objective of this study was to assess the knowledge, attitudes and reported practices relating to HIV/AIDS and STIs among private and public sector health care providers providing clinical services in areas where women sell sex. This was an exploratory quantitative study, where a structured questionnaire was administered in face-to-face interviews with 200 HCPs from the public and private sectors. Knowledge about AIDS and correct diagnosis of STIs were defined as according to the national guidelines of NACP. Pearson's chi-square analysis was performed to test associations between predictors and level of knowledge of STIs in each group separately. Multivariate logistic regression analysis was employed to indicate predicting factors for correct management of STIs. Forty-five percent of the HCPs had correct knowledge about the transmission and prevention of HIV, whereas 21% had seen a patient with advanced HIV infection, only two HCPs had been trained to manage such cases and 82% were not aware of syndromic management of STIs. Only 10% could cite the 'correct treatment' of gonorrhoea, syphilis and vaginal discharge. The odds of having the 'correct knowledge' of diagnosing gonorrhoea and syphilis were 2.1 (CI 95%, 1.2-3.8) if the HCP was a female medical doctor working in public sector. Further intensive training is needed to improve the ability of relevant HCPs to correctly diagnose and effectively treat patients

  17. Severe Dermatophytosis and Acquired or Innate Immunodeficiency: A Review

    Claire Rouzaud

    2015-12-01

    Full Text Available Dermatophytes are keratinophilic fungi responsible for benign and common forms of infection worldwide. However, they can lead to rare and severe diseases in immunocompromised patients. Severe forms include extensive and/or invasive dermatophytosis, i.e., deep dermatophytosis and Majocchi’s granuloma. They are reported in immunocompromised hosts with primary (autosomal recessive CARD9 deficiency or acquired (solid organ transplantation, autoimmune diseases requiring immunosuppressive treatments, HIV infection immunodeficiencies. The clinical manifestations of the infection are not specific. Lymph node and organ involvement may also occur. Diagnosis requires both mycological and histological findings. There is no consensus on treatment. Systemic antifungal agents such as terbinafine and azoles (itraconazole or posaconazole are effective. However, long-term outcome and treatment management depend on the site and extent of the infection and the nature of the underlying immunodeficiency.

    Full Text Available OBJETIVO: Analisar a freqüência da tuberculose e das outras principais doenças oportunistas definidoras de síndrome da imunodeficiência adquirida, no momento em que estes casos são notificados, no Município do Rio de Janeiro. MÉTODOS: Análise do banco de dados do Sistema de Vigilância Epidemiológica do Programa de Doenças Sexualmente Transmissíveis e Síndrome da Imunodeficiência Adquirida da Cidade do Rio de Janeiro, no período de 1993 a 2002. RESULTADOS: A expansão da definição de casos de síndrome da imunodeficiência adquirida ocorrida em 1998 criou um aumento substancial no número de casos notificados de síndrome da imunodeficiência adquirida, principalmente por aqueles que passaram a ser definidos pelo critério imunológico. Dentre os casos de síndrome da imunodeficiência adquirida que foram definidos apenas por doença, a candidíase em suas diversas formas manteve-se como a doença oportunista de maior freqüência no momento da notificação. Embora a pneumonia por Pneumocystis carinii se apresentasse como a segunda doença mais freqüente na maioria dos anos observados, a partir de 2001, a tuberculose ultrapassou-a em freqüência, tornando-se a segunda doença mais freqüente no momento da notificação dos casos de síndrome da imunodeficiência adquirida. CONCLUSÃO: Apesar da diminuição do número de casos de síndrome da imunodeficiência adquirida definidos por doença, a tuberculose manteve-se como um importante evento definidor dessa síndrome, sendo atualmente de ocorrência mais freqüente do que a pneumonia por Pneumocystis carinii e a toxoplasmose, provavelmente por sua alta taxa de prevalência na cidade.OBJECTIVE: To analyze the frequency of tuberculosis and of the other principal opportunistic infections defining acquired immunodeficiency syndrome at the time such cases were reported in the city of Rio de Janeiro, Brazil.

O emprego da técnica de imunoistoquímica auxilia no diagnóstico das esofagites virais e torna possível detectar o citomegalovírus em esôfagos normais à endoscopia e/ou ao exame histopatológico.BACKGROUND: Almost all patients with acquired immunodeficiency virus syndrome will have gastrointestinal symptoms during the course of their illness. The high prevalence and complications of esophagitis are well documented. AIM: Graduate esophagitis; identify microorganisms like Candida sp, cytomegalovirus, herpesvirus and mycobacteria; identify by immunohistochemical staining viral agents cytomegalovirus, herpesvirus I, herpesvirus II, Epstein-Barr Virus, human papilloma virus and human immunodeficiency virus; verify how immunohistochemistry changes the profile of esophagitis; verify the association between the histological and endoscopical findings; verify the relevance of the number of fragments studied in the characterization of the histological agents. METHODS: We studied retrospectively esophageal biopsies in 227 patients with acquired immunodeficiency virus syndrome using hematoxylin and eosin, PAS (periodic acid of Schiff, Groccott and Ziehl-Nielsen stains and immunoperoxidase stains to detect opportunistic agents. Endoscopic aspects were studied. RESULTS: The non-specific esophagitis grade III, in the inferior third of the esophagus, was the most frequent type. Candida sp was the most frequent agent, followed by viruses cytomegalovirus, herpesvirus and mycobacteria. The presence of plaque and ulceration suggested the diagnosis of esophageal candidiasis and cytomegalovirus esophagitis. Immunohistochemical allowed the characterization of cytomegalovirus and of herpesvirus in those cases where other techniques could not achieve it, furthermore the cytomegalovirus was also found in histological normal cases, making the use of this technique advisable in routine diagnosis. The herpesvirus I was not found isolated but associated to

    Full Text Available Human immunodeficiency virus (HIV-positive patients have a greater prevalence of coinfection with human papillomavirus (HPV is of high oncogenic risk. Indeed, the presence of the virus favours intraepithelial squamous cell lesion progression and may induce cancer. The aim of this study was to evaluate the prevalence of HPV infection, distribution of HPV types and risk factors among HIV-positive patients. Cervical samples from 450 HIV-positive patients were analysed with regard to oncotic cytology, colposcopy and HPV presence and type by means of polymerase chain reaction and sequencing. The results were analysed by comparing demographic data and data relating to HPV and HIV infection. The prevalence of HPV was 47.5%. Among the HPV-positive samples, 59% included viral types of high oncogenic risk. Multivariate analysis showed an association between HPV infection and the presence of cytological alterations (p = 0.003, age greater than or equal to 35 years (p = 0.002, number of partners greater than three (p = 0.002, CD4+ lymphocyte count < 200/mm3 (p = 0.041 and alcohol abuse (p = 0.004. Although high-risk HPV was present in the majority of the lesions studied, the low frequency of HPV 16 (3.3%, low occurrence of cervical lesions and preserved immunological state in most of the HIV-positive patients were factors that may explain the low occurrence of precancerous cervical lesions in this population.

We present two cases of GS and secondary immunodeficiency due to anatomical defects characteristic of this disorder. Case 1 (3-year-old female averaged 6 episodes of sinusitis and otitis media per year. Case 2 (7-year-old female also had recurrent otitis media, an episode of bacterial pneumonia, and 2 episodes of bacterial meningitis. Their immune evaluation included a complete blood count with differential, serum immunoglobulin levels and specific antibody concentrations, lymphocyte phenotyping, and mitogen and antigen responses, the results of which were all within normal ranges. Both children demonstrated major structural abnormalities of the inner and middle ear structures, retention of fluid in mastoid air cells, and chronic sinusitis by computed tomography. These two cases illustrate how a genetically-associated deviation of the middle ear cleft can cause recurrent infections and chronic inflammation of the middle ear and adjacent sinuses, even meninges, leading to a greatly reduced quality of life for the child and parents.

  13. The acquired hyperostosis syndrome. Pt. 2

    In the second part of this publication, we describe some additional findings in cases of sternocostoclavicular hyperostosis (SCCH). These include focal hyperostosis of the spine, in the pelvis and in the extremities and psoriatric skin lesions and severe forms of acne (acne conglobata, acne fulminans). An analysis of our 13 patients and of the relevant literature indicates that the hyperostosis is due to increased bone metabolism and heterotopic ossification of fibrous tissue and that these are the pathogenic bases of the changes in the axial skeleton, the pelvis and the bones of the extremities. We have suggested a scheme which would categorise the syndrom into complete, incomplete and possibly acquired forms. (orig./GDG)

    Sweet\\'s syndrome (SS), a rare reactive neutrophilic dermatosis, has been reported to occur in association with a variety of systemic disorders, categorized by von den Diesch into idiopathic, paraneoplastic, pregnancy and parainflammatory subgroups. The parainflammatory group has been well defined, and includes a wide spectrum of infectious triggers and disorders of immune dysregulation. To date, however, no cases of SS have been described in the context of common variable immunodeficiency (CVID). We report a case of paediatric-onset SS, previously reported as idiopathic, with a subsequent diagnosis of CVID.

    1996-05-01

    An in vitro coculture model system of CD34+ stem cells and allogenic cultured thymic epithelia fragments was used to evaluate thymocyte differentiation in a 9-month-old child of Amish descent with Nezelof syndrome. Though the patient`s stem cells differentiate to acquire normal expression of CD2 and CD7, later steps of maturation were abnormal. There was detectable but reduced expression of CD3 and CD4 phenotypes. CD44+ expression, however, was markedly reduced. CD44 is an adhesion molecule, interacting with the matrix ligands hyaluronan and fibronectin, and is expressed early in thymocyte differentiation and subsequently in mature T cells. It is hypothesized that abnormal expression of CD44 in a variant of severe combined immunodeficiency, Nezelof`s syndrome, interferes with normal thymocyte and thymic epithelial interaction, which leads to abnormal thymocyte differentiation. 35 refs., 2 figs., 3 tabs.

METHODS: This is a qualitative and exploratory study; data were collected between July and November 2008, through interviews with five family members of children with AIDS, who were sheltered in an institution of support. RESULTS: The meaning of statements were coded and analyzed, resulting in three categories: experiencing the order, disorder and the organization of a family member of a child with AIDS; dialoguing with the assurance and doubt of disclosing the diagnosis to a child with AIDS; and, facing the limits of unknown, decadence, live and death. CONCLUSION: It was revealed that being a family member and caring for a child with AIDS, is a complex process that requires an understanding of multiple factors (such as: biological, psychological, social, spiritual, and the ones related to the disease and the patient and the attitude of caring focused on the human being - a unique being, complex and multidimensional.

    A 47-year-old male with acquired immune deficiency syndrome (AIDS) presented with multiple hyperpigmented papules and nodules on both ankles, dorsum of bilateral feet and soles. It was associated with mild itching and pain. The patient was diagnosed with human immunodeficiency virus (HIV) in 2007. First-line antiretroviral therapy (ART) was started in 2009 to which he responded initially. He was shifted to second-line ART 11 months ago in March 2015 due to treatment failure as suggested by CD4 count of 50 cells/mm(3). The present skin lesions started 2 months after the initiation of second-line ART. Differential diagnoses considered were Kaposi's sarcoma and immune reconstitution inflammatory syndrome (IRIS) related infections, but biopsy was suggestive of erythema elevatum diutinum (EED). Patient was started on oral dapsone 100 mg/day and increased to 200 mg/day to which he is responding gradually. In the present case, appearance of the lesions after initiation of second-line ART coupled with increase in CD4 count and decrease of viral load below undetectable level suggest that EED could be an IRIS.

  7. Adolescents and human immunodeficiency virus infection.

    Anderson, J R

    1992-12-01

    As of March 31, 1992, individuals 13 to 19 years of age had been diagnosed with acquired immunodeficiency syndrome; over one third were diagnosed in the past 2 years alone. Because of the long incubation period from initial infection to acquired immunodeficiency syndrome diagnosis, the majority of young adults with acquired immunodeficiency syndrome were probably initially infected as adolescents. In 1991, 34% of adolescents with acquired immunodeficiency syndrome were female, and their predominant mode of transmission was heterosexual contact. Human immunodeficiency virus seroprevalence studies of adolescents show a male-to-female ratio approaching 1:1, with many human immunodeficiency virus-infected adolescent women identifying none of the standard risk. Factors such as sexual and drug experimentation, risk taking, and sense of invulnerability so characteristic of adolescence put adolescents at special risk for human immunodeficiency virus. There is no published information on if or how clinical manifestations of human immunodeficiency virus disease in adolescents might differ from those seen in adults. Medical care should be broad-based and should include access to clinical trials for new drug treatments. General knowledge levels about acquired immunodeficiency syndrome are high among US adolescents, but behavioral changes have lagged behind. All adolescents should be targeted for intensive education about human immunodeficiency virus along with interventions designed to enhance their general coping, communication, and decision-making skills.

    Artemis, DNA ligase IV, DNA protein kinase catalytic subunit, and Cernunnos/XLF genes in nonhomologous end joining pathways of DNA repair mechanisms have been identified as responsible for radiosensitive SCID. Here, we present a 3-year-old girl patient with severe growth retardation, bird-like face, recurrent perianal abscess, pancytopenia, and polydactyly. Firstly, she was thought as Fanconi anemia and spontaneous DNA breaks were seen on chromosomal analysis. After that DEB test was found to be normal and Fanconi anemia was excluded. Because of that she had low IgG and IgA levels, normal IgM level, and absence of B cells in peripheral blood; she was considered as primary immunodeficiency, Nijmegen breakage syndrome. A mutation in NBS1 gene was not found; then Cernunnos/XLF deficiency was investigated due to clinical similarities with previously reported cases. Homozygous mutation in Cernunnos/XLF gene (NHEJ1) was identified. She is now on regular IVIG prophylaxis and has no new infection. Fully matched donor screening is in progress for bone marrow transplantation which is curative treatment of the disease. In conclusion, the patients with microcephaly, bird-like face, and severe growth retardation should be evaluated for hypogammaglobulinemia and primary immunodeficiency diseases. PMID:24511403

  11. Tuberculosis and the acquired immune deficiency syndrome in South Brazil

    Tuberculosis and the acquired immune deficiency syndrome in South Brazil. The authors studied the incidence of tuberculosis in South Brazilian patients with acquired immune deficiency syndrome from January 1985 to June 1988. During this period, tuberculosis occurred in 10.3% of acquired immune deficiency syndrome patients. The socioeconomic conditions and the incidence of disease in the population were not confirmed as a potential risk for tuberculosis infection. Chest radiographs revealed pulmonary infiltrates in six patients, hilar and/or mediastinal adenopathy in three, and pleural effusion in two. The two remaining patients had pulmonary consolidation associated with other features. None of these patients presented pulmonary cavitation or radiographic findings of typical reactivation of pulmonary tuberculosis. (author)

    Full Text Available OBJETIVO: Descrever os efeitos do tratamento fisioterapêutico na prevenção de complicações respiratórias de uma criança com síndrome da imunodeficiência adquirida, que apresentava pneumatocele gigante. DESCRIÇÃO DO CASO: Criança com oito anos de idade, do sexo feminino, encaminhada para acompanhamento fisioterapêutico em hospital universitário devido a quadro de hipersecreção pulmonar, histórico de pneumonias e presença de pneumatocele gigante. A conduta fisioterapêutica incluiu técnicas de higiene brônquica ativa, envolvendo fluxo aéreo expiratório, com o intuito de promover a desobstrução pulmonar sem causar risco de complicações à criança. O seguimento foi multiprofissional e direcionado à prevenção de infecções recorrentes e de ruptura da bolha, que tornariam necessária a internação hospitalar. Durante o acompanhamento, o quadro pulmonar manteve-se estável, sem aumento ou ruptura da pneumatocele, radiograficamente visível. COMENTÁRIOS: A atuação da fisioterapia respiratória nos casos de pneumatocele gigante não está definida na literatura. Não há, até o momento, evidências de seus efeitos benéficos, bem como diretrizes a respeito dos métodos mais eficientes e seguros. Ao contrário, muito se discute sobre os riscos e complicações decorrentes dessa intervenção. No presente caso, a assistência fisioterapêutica regular foi importante para garantir a estabilidade do quadro pulmonar da criança, sendo necessários estudos com desenho metodológico apropriado para verificação de eficácia clínica.OBJECTIVE: To describe the effects of chest physiotherapy in preventing respiratory complications in a child with acquired immunodeficiency syndrome and a giant pneumatocele.

  16. Chest radiography patterns in 75 adolescents with vertically-acquired human immunodeficiency virus (HIV) infection

    Aim: To evaluate lung disease on chest radiography (CR), the relative frequency of CR abnormalities, and their clinical correlates in adolescents with vertically-acquired human immunodeficiency virus (HIV) infection. Materials and methods: CRs of 75 patients [59 inpatients (33 males; mean age 13.7 ± 2.3 years) and 16 outpatients (eight males; mean age 14.1 ± 2.1 years)] were retrospectively reviewed by three independent observers. The overall extent of disease (to the nearest 5%), its distribution, and the proportional extents (totalling 100%) of different radiographic patterns (including ring/tramline opacities and consolidation) were quantified. CR features and clinical data were compared. Results: CRs were abnormal in 51/75 (68%) with 'extensive' disease in 38/51 (74%). Ring/tramline opacities and consolidation predominated (i.e., proportional extent >50%) in 26 and 21 patients, respectively. Consolidation was significantly more common in patients hospitalized primarily for a respiratory illness than patients hospitalized for a non-respiratory illness or in outpatients (p 2 for trend); by contrast, ring/tramline opacities did not differ in prevalence across the groups. On stepwise logistic regression, predominant consolidation was associated with progressive dyspnoea [odds ratio (OR) 5.60; 95% confidence intervals (CI): 1.60, 20.1; p < 0.01] and was associated with a primary respiratory cause for hospital admission (OR: 22.0; CI: 2.7, 181.1; p < 0.005). Ring/tramline opacities were equally prevalent in patients with and without chronic symptoms and in those admitted to hospital with respiratory and non-respiratory illness. Conclusion: In HIV-infected adolescents, evaluated in secondary practice, CR abnormalities are prevalent. The presence of ring/tramline opacities, believed to reflect chronic airway disease, is not linked chronic respiratory symptoms.

    Full Text Available Aims and Objectives : To assess the prevalence of metabolic syndrome (MetS in human immunodeficiency virus (HIV positive patients. Prevalence of MetS was compared in patients who were not on highly active antiretroviral therapy (HAART to patients who were on HAART. Materials and Methods: Seventy HIV positive cases were studied. Pregnant and lactating women, patients on drugs other than HAART known to cause metabolic abnormalities and those having diabetes or hypertension were excluded. Cases were evaluated for MetS by using National Cholesterol Education Program Adult Treatment Panel-III. Results: 47 cases were on HAART and 23 cases were not on HAART. Fasting Blood Glucose ≥100 mg/dl was present in 28.6% cases, out of whom 27.7% were on HAART and 30.4% were not on HAART (P = 0.8089. 12.9% cases had BP ≥130/≥85 mm Hg, out of whom 14.9% were on HAART and 8.7% were not on HAART (P = 0.4666. 42.9% cases had TG ≥150 mg/dl, out of whom 44.7% were on HAART and 39.1% were not on HAART (P = 0.6894. HDL cholesterol was low (males <40 mg/dl, females <50 mg/dl in 50% cases, out of whom 55.3% were on HAART and 39.1% were not on HAART (P = 0.2035. Conclusions: Prevalence of MetS was 20%. Majority of patients had only one component of MetS (32.9%. Low HDL was present in 50%, followed by raised triglycerides in 42.9%. Waist circumference was not increased in any of the patients. There was no statistically significant difference between those on HAART and those not on HAART in distribution of risk factors and individual components of MetS.

    2004-01-01

    Full Text Available Acute febrile neutrophilic dermatosis (AFND, commonly known as Sweet’s syndrome, is a disorder seen in adult females, being extremely rare in children. Typical features include spiky fever, sudden eruption of raised painful erythematous to plum-colored nodules and plaques, neutrophilic leucocytosis, a dermal neutrophili infiltrate an a rapid response to systemic steroid. The eruption is believed to represent a hypersensitivity reaction to an antecedent infection or malignancy. There have been rare reports of acquired cutis laxa (Marshall’s syndrome following Sweet’s syndrome. We report one such case of Sweet’s syndrome leading to acquired cutis laxa (Marshall’ syndrome in a child.

  3. Anthracyclines and Acquired Long QT Syndrome. A Case Report

    Carlos Rodríguez Armada

    2014-12-01

    Full Text Available Acquired long QT syndrome results from secondary causes and can be caused by more than 100 non-antiarrhythmic drugs. Cardiac arrest due to Torsades de pointes induced by drugs causing prolonged QT syndrome is a rare but potentially fatal event, even in hospitals. The case of a 47-year-old patient diagnosed with non-Hodgkin lymphoma admitted to the hematology department of the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos is presented. The patient had been previously treated with anthracyclines and developed episodes of palpitations and syncope later. The treatment included monitoring the patient, avoiding other QT prolonging agents and administrating magnesium sulfate and potassium chloride with a proper maintenance of the fluid and acid-base balance. The presentation of this case aims at motivating interest in new reports on the subject and establishing a direct causal relationship through the evidence provided by new experiences.

  7. Acquired long QT syndrome: a focus for the general pediatrician.

    Marzuillo, Pierluigi; Benettoni, Alessandra; Germani, Claudio; Ferrara, Giovanna; D'Agata, Biancamaria; Barbi, Egidio

    2014-04-01

    Acquired long QT syndrome (LQTS) is a disorder of cardiac repolarization most often due to specific drugs, hypokalemia, or hypomagnesemia that may precipitate torsade de pointes and cause sudden cardiac death. Common presentations of the LQTS are palpitations, presyncope, syncope, cardiac arrest, and seizures. An abnormal 12-lead electrocardiogram obtained while the patient is at rest is the key to diagnosis. The occurrence of drug-induced LQTS is unpredictable in any given individual, but a common observation is that most patients have at least 1 identifiable risk factor in addition to drug exposure. The cornerstone of the management of acquired LQTS includes the identification and discontinuation of any precipitating drug and the correction of metabolic abnormalities, such as hypokalemia or hypomagnesemia. Most of the episodes of torsade de pointes are short-lived and terminate spontaneously. We propose a management protocol that could be useful for the daily practice in the emergency pediatric department to reduce the risk of acquired QT prolongation. PMID:24694881

    2006-05-01

    We report on a case of herpes simplex virus (HSV) type 1 colitis in a 69-year-old patient with common variable immunodeficiency syndrome. A treatment with polyvalent immunoglobulins was discontinued in April 2001. In March 2004 she developed chronic diarrhoea related to rectosigmoidal and caecal ulcerations. In November 2004, HSV was recovered in tissue culture from colonic biopsies. Valaciclovir was then started, leading the patient to clinical remission at day 4, and continued for a 6-week course (without any secondary antiviral prophylaxis). Colonic biopsies were negative for HSV by tissue culture and PCR within 3 weeks of antiviral treatment. Intravenous polyvalent immunoglobulin infusions were readministered within the third week of antiviral treatment. She has declared no clinical event since this period. Three months after the antiviral treatment was achieved, a rectosigmoidoscopy showed an ad-integrum macroscopic and histological mucosal healing whereas PCR was negative for HSV in the colonic tissue. As a large proportion of patients with common variable immunodeficiency syndrome present not only as a humoral immunodeficiency but also as a defect in the cellular immunity compartment (with T-cell deficits), HSV, as well as cytomegalovirus, should be investigated in patients with common variable immunodeficiency syndrome presenting colitis.

    2014-01-01

    Full Text Available Acquired von Willebrand syndrome (AVWS is an uncommon, underdiagnosed, and heterogeneous disease which is increasingly recognized as a cause of bleeding diatheses. Systemic lupus erythematosus (SLE is an infrequent cause of AVWS. Herein, we report a case of AVWS diagnosed during the initial presentation of SLE in a previously healthy young man with no family history of bleeding diathesis who presented with worsening epistaxis, gastrointestinal bleeding, and anasarca. He was found to have severe anemia and prolonged activated partial thromboplastin time (aPTT with severely decreased levels of von Willebrand factor (VWF measurements in addition to markedly decreased factor VIII levels. Further evaluation revealed nephrotic syndrome and interstitial lung disease due to SLE. He initially received combination therapy with intravenous immunoglobulin (IVIG and von Willebrand factor/factor VIII concentrates without significant improvement. Treatment with steroids, cyclophosphamide, and rituximab was followed by clinical improvement evidenced by cessation of bleeding. The short follow-up did not allow us to definitely prove the therapeutic effect of immunosuppressive treatment on AVWS in SLE patients. This case adds to the literature supporting the relationship between AVWS and SLE and highlights the importance of combination therapy in the treatment of severe AVWS as well as the role of IVIG, cyclophosphamide, and rituximab in AVWS associated with SLE.

    Full Text Available Abstract Introduction Few cases of Epstein-Barr virus myelitis have been described in the literature. Multi-centric Castleman's disease is a lymphoproliferative disorder that is well known for its associations with the human immunodeficiency virus, human herpes virus 8, and Kaposi's sarcoma. The concurrent presentation of these two diseases in a patient at the same time is extremely unusual. Case Presentation We describe the case of a 43-year-old Caucasian man with acquired immune deficiency syndrome who presented with fever, weight loss and diffuse lymphadenopathy, and was diagnosed with multi-centric Castleman's disease. He presented three weeks later with lower extremity weakness and urinary retention, at which time cerebrospinal fluid contained lymphocytic pleocytosis and elevated protein. Magnetic resonance imaging demonstrated abnormal spinal cord signal intensity over several cervical and thoracic segments, suggesting the diagnosis of myelitis. Our patient was ultimately diagnosed with Epstein-Barr virus myelitis, as Epstein-Barr virus DNA was detected by polymerase chain reaction in the cerebrospinal fluid. Conclusion To the best of our knowledge, this is the first case of multi-centric Castleman's disease followed by acute Epstein-Barr virus myelitis in a human immunodeficiency virus-infected patient. Clinicians caring for human immunodeficiency virus-infected patients should be vigilant about monitoring patients with increasing lymphadenopathy, prompting thorough diagnostic investigations when necessary.

    2015-03-01

    The spread of human immunodeficiency virus (HIV) infection within Africa led to marked increases in numbers of cases of tuberculosis (TB), and although the epidemic peaked in 2006, there were still 1.8 million new cases in 2013, with 29.2 million prevalent cases. Half of all TB cases in Africa are in those with HIV co-infection. A brief review of the well-documented main immunological mechanisms of HIV-associated increased susceptibility to TB is presented. However, a new threat is facing TB control, which presents itself in the form of a rapid increase in the number of people living with type II diabetes mellitus (T2DM), particularly in areas that are already hardest hit by the TB epidemic. T2DM increases susceptibility to TB threefold, and the TB burden attributable to T2DM is 15%. This review addresses the much smaller body of research information available on T2DM-TB, compared to HIV-TB comorbidity. We discuss the altered clinical presentation of TB in the context of T2DM comorbidity, changes in innate and adaptive immune responses, including lymphocyte subsets and T-cell phenotypes, the effect of treatment of the different comorbidities, changes in biomarker expression and genetic predisposition to the respective morbidities, and other factors affecting the comorbidity. Although significant gains have been made in improving our understanding of the underlying mechanisms of T2DM-associated increased susceptibility, knowledge gaps still exist that require urgent attention.

    Anaplastic large cell lymphoma (ALCL) is an uncommon disease, accounting for <5% of all cases of non-Hodgkin's lymphoma. We report a case of 48-year-old male who presented a clinically benign swelling in the right anterior palatal region since last 2 months. Radiographic evaluation showed no bone loss in palatal area. Histological and radiological examination was in favor of a peripheral reactive lesion like pyogenic granuloma or a benign salivary gland tumor. Immunohistochemistry confirmed the diagnosis of anaplastic lymphoma kinase-negative (ALK(-)) ALCL. Further laboratory tests ELISA for human immunodeficiency virus (HIV) and CD4 cell count was done which showed positivity for HIV. To the best of our knowledge, it is the first case of ALK(-) ALCL in the hard palate presenting as the first clinical manifestation of acquired immune deficiency syndrome. PMID:27041916

A cohort of 65 patients (17.6 ± 2 years at the Federal University of Rio de Janeiro, Brazil, were examined for pubertal development, nutrition, serum parathormone and serum 25-hydroxyvitamin D [s25(OHD]. s25(OHD levels < 30 ng/mL (< 75 nmol/L were defined as VitD insufficiency. CD4+ T-cell counts and viral load, history of worst clinical status, immunologic status as nadir, current immunologic status, and antiretroviral (ART regimen were also evaluated as risk factors for VitD insufficiency. Mean s25(OHD was 37.7 ± 13.9 ng/mL and 29.2% had VitD insufficiency. There was no difference between VitD status and gender, age, nutritional status, clinical and immunological classification, and type of ART. Only VitD consumption showed tendency of association with s25(OHD (p = 0.064.

    Full Text Available Abstract Background PHACE is a neurocutaneous syndrome associated with: Posterior fossa brain malformations, large “segmental” facial hemangiomas, arterial cerebrovascular-, cardiovascular-, and eye anomalies. Case vignette We are reporting a girl with PHACE syndrome. The patient had a congenital right-sided facial hemangioma with plaque-morphology. At age 11 years and 2 months she presented with short stature, markedly decreased growth velocity and signs and symptoms suggestive of hypothyroidism. Magnetic Resonance Imaging (MRI of the brain revealed complex structural and cerebrovascular arterial anomalies, including an empty sella. Testing of pituitary function revealed multiple pituitary dysfunctions, including absolute growth hormone deficiency, hypogonadotropic hypogonadism, central hypothyroidism, and secondary adrenal insufficiency. Conclusions This case suggests the necessity to screen all patients with PHACE syndrome and intracranial malformations for pituitary dysfunction at regular intervals.

  11. Experimental oral polio vaccines and acquired immune deficiency syndrome.

    Hooper, E

    2001-06-29

    The simian immunodeficiency virus (SIV) of the common chimpanzee is widely acknowledged as the direct ancestor of HIV-1. There is increasing historical evidence that during the late 1950s, kidneys were routinely excised from central African chimpanzees by scientists who were collaborating with the polio vaccine research of Dr Hilary Koprowski, and sent - inter alia - to vaccine-making laboratories in the USA and Africa, and to unspecified destinations in Belgium. While there is no direct evidence that cells from these kidneys were used as a substrate for growing Dr Koprowski's oral polio vaccines, there is a startling coincidence between places in Africa where his CHAT vaccine was fed, and the first appearances in the world of HIV-1 group M and group-M-related AIDS. Because of the enormous implications of the hypothesis that AIDS may be an unintended iatrogenic (physician-caused) disease, it is almost inevitable that this theory will engender heated opposition from many of those in the scientific establishment, and those with vested interests.

    2012-01-01

    The Immunodeficiency, Centromeric instability, Facial anomalies (ICF) syndrome is an autosomal recessive disease presenting with immunodeficiency secondary to hypo- or agammaglobulinemia, developmental delay, and facial anomalies. Centromeric instability is the cytogenetic hallmark of the disorder which results from targeted chromosomal rearrangements related to a genomic methylation defect. We describe a patient carrying a homozygous mutation of the ZBTB24 gene, which has been recently shown to be responsible for ICF syndrome type 2. Our patient presented with intellectual disability, multiple café-au-lait spots, and a large cerebral arachnoidal cyst. Although laboratory signs of impaired immune function, such as reduced serum IgM were detected, our patient did not present clinical manifestations of immunodeficiency. Brain malformations have not been reported so far in ICF syndrome and it can be speculated that ZBTB24 mutations may alter cerebral development. Nevertheless, we cannot rule out that the presence of the cerebral cyst in the patient is coincidental. In summary, our patient illustrates that clinical evidence of immunodeficiency is not a universal feature of ICF2 syndrome type 2 and suggests that brain malformations may be present in other ICF cases.

  13. Immune dysregulation, Polyendocrinopathy, Enteropathy, X-linked (IPEX syndrome: a paradigm of immunodeficiency with autoimmunity

    Federica eBarzaghi

    2012-07-01

    Full Text Available Immune dysregulation, Polyendocrinopathy, Enteropathy, X-linked (IPEX syndrome is a rare monogenic primary immunodeficiency (PID due to mutations of FOXP3, a key transcription factor for naturally occurring (n regulatory T (Treg cells. The dysfunction of Treg cells is the main pathogenic event leading to the multi-organ autoimmunity that characterizes IPEX syndrome, a paradigm of genetically determined PID with autoimmunity. IPEX has a severe early onset and can become rapidly fatal within the first year of life regardless of the type and site of the mutation. The initial presenting symptoms are severe enteritis and/or type 1 diabetes mellitus, alone or in combination with eczema and elevated serum IgE. Other autoimmune symptoms, such as hypothyroidism, cytopenia, hepatitis, nephropathy, arthritis, and alopecia, can develop in patients who survive the initial acute phase.The current therapeutic options for IPEX patients are limited. Supportive and replacement therapies combined with pharmacological immunosuppression are required to control symptoms at onset. However, these procedures can allow only a reduction of the clinical manifestations without a permanent control of the disease. The only known effective cure for IPEX syndrome is haematopoietic stem cell transplantation, but it is always limited by the availability of a suitable donor and the lack of specific guidelines for bone marrow transplant in the context of this disease.This review aims to summarize the clinical histories and genomic mutations of the IPEX patients described in the literature to date. We will focus on the clinical and immunological features that allow differential diagnosis of IPEX syndrome and distinguish it from other PID with autoimmunity. The efficacy of the current therapies will be reviewed, and possible innovative approaches, based on the latest highlights of the pathogenesis to treat this severe primary autoimmune disease of childhood, will be discussed.

  16. Pulmonary cysts associated with pneumocystis carinii pneumonia in patients with the acquired immunodeficiency syndrome

    Diffuse bilateral interstitial infiltrates are typically seen with Pneumocystis carinii pneumonia (PCP). Atypical radiographic patterns exist. The authors describe a new pattern of thin-walled, air-filled pneumatoceles occurring with PCP. Appearance, natural history, and clinical significance of these pneumatoceles are discussed. Chest radiographs in 100 patients with PCP were retrospectively analyzed. Cysts were present in ten cases. They appear as thin-walled, air-filled cavities without intracystic contents and behave like pneumatoceles of other infectious causes. The time of cyst appearance is variable. No particular long segment is favored. The cause is unknown. Rupture may lead to spontaneous pneumothroax

    Intestinal microsporidiosis with Enterocytozoon bieneusi was diagnosed in three of 18 HIV-infected patients with chronic diarrhoea. In two cases all known stages of the life cycle of E. bieneusi (merogonial plasmodia, sporogonial plasmodia, sporoblasts, spores) were found in duodenal biopsies by electron microscopical examination, whereas in the third case only merogonial and sporogonial stages were seen. Spores were also visible by light microscopy in semithin sections. Two patients were treated with albendazole (2 x 400 mg/day for 4 weeks) but showed no response. These findings underline the concept of the worldwide distribution of this parasite and verify that it is also frequent in Germany. PMID:7698840

    PURPOSE: To evaluate and delineate the characteristics of cerebral toxoplasmosis lesions using a combination of magnetic resonance (MR) spectroscopy, diffusion, and perfusion studies. MATERIAL AND METHODS: A total of 8 patients with 23 lesions were evaluated on a 1.5-T MR system. Diffusion-weighted imaging (DWI) was performed with three 'b' values of 50, 500, and 1000 s/mm2, and the apparent diffusion coefficient maps were calculated. The diffusion-weighted appearances and the T2-weighted MR appearances of the lesions were compared. MR spectroscopy was performed using the point-resolved single-voxel technique with two TE values of 135 ms and 270 ms. Perfusion studies were carried out using the dynamic contrast-enhanced technique, and the relative cerebral blood volume maps were qualitatively and quantitatively analyzed. RESULTS: DWI revealed the majority of the lesions as having increased diffusion within their necrotic centers, with the ADC ranging from 0.5 to 3.01 (mean {+-} SD: 1.49 {+-} 0.7). All the lesions revealed a predominant lipid peak on MR spectroscopy and were extremely hypovascular on perfusion MR studies. CONCLUSION: MR diffusion, spectroscopy, and perfusion studies help in characterizing toxoplasmosis lesions and, in most cases, can be used in combination to help establish the diagnosis of toxoplasmosis.

  20. CT findings of abdominal tuberculosis in patients with acquired immunodeficiency syndrome

    Objective: To study the CT findings of abdominal tuberculosis in patients with AIDS. Methods: CT imaging features of abdominal tuberculosis in 33 patients with AIDS were retrospectively analyzed. Results: Abdominal lymph adenopathy were observed in 23 cases (69.7%, 23/33). Hepatosplenomegaly were observed in 10 cases (30.3%, 10/33). Multiple low density nodes in spleen were observed in 14 cases (42.4%,14/33) including 9 cases of diffuse, low density nodes (27.3%, 9/33). Low density lesions in liver were observed in 7 cases (21.2%, 7/33) including a case of tuberculous abscess (3.0%, 1/33). Peritoneum and epiploon involvements were found in 5 cases (15.2%, 5/33) with associated ascites in 2 cases (6.1%, 2/33). Thickening of intestines wall were observed in 4 cases (12.1%, 4/33). Destruction of lumbar vertebra with cold abscess was observed in 1 case (3.0%, 1/33). Abscess in psoas was observed in 1 case (3.0%, 1/33). Conclusion: Abdominal tuberculosis in patients with AIDS usually involves multiple organs in the abdomen. CT has an important role in the detection and following up examination of these lesions.

    2009-05-01

    Full Text Available Bioethical aspects related with the prevention, diagnosis and treatment of patients with AIDS are present in the Cuban strategy to fight the epidemic. Through the revision of the essentials and principles of Bioethics, we analyze the problems that doctors face when treating these patients and aspects related with education for health in the case of this disease. It also outlines the association between these principles and the disposition, manifested or not, of theses patients to be part of some researches. This infection should be the target of permanent analysis by the Bioethics due to the constant challenges that it represent for medical staff and for society, either for the prevention, treatment and care, or for other kids of actions. Cuba has exceptional results in this field.

    We report a series of thirteen patients with nervous system complications out of a total of thirty AIDS patients admitted to our hospital over the last two years for which CT and/or MRI have been performed. Five were homosexual men and eight patients (5 men, 3 women) were of African origin (Zaire and Rwanda) (n=5) or had had sexual intercourse with the local African population (n=3). The nervous system complications encountered included: Toxoplasma gondii brain abscess (2 patients); cryptococcus neoformans meningitis+toxoplasmosis (1 patient); toxoplasmosis+lymphoma (2 patients); progressive multifocal leucoencephalopathy (1 patient); lymphocytic meningitis or encephalitis (3 patients); lymphoma (1 patient); polyradiculoneuritis (3 patients). Three of thirteen patients had multiple intracranial abnormalities: One had concomitant intraparenchymal toxoplasma abscess and cryptococcal meningitis; in one patient a lymphoma developed after the successful medical treatment of a toxoplasma abscess; conversely, one patient developed a toxoplasma abscess two years after mediastinal radiotherapy for a systemic non-Hodgkin lymphoma. In conclusion, in our experience, nervous system toxoplasmosis is the most frequent AIDS related CNS complication. Our series demonstrates the high frequency of a second neurological disease occurring either concomitantly or separately. In these cases, while CT may readily identify the intracranial abnormalities, it contributes little towards an etiological diagnosis. Finally, our series illustrates the importance of a central African endemic focus for AIDS.

    2012-02-01

    Full Text Available OBJECTIVES: To compare epidemiological aspects of young (15 to 49 years old and older (more than 50 years old AIDS patients. METHODS: We analyzed 511,633 AIDS cases notified to the Brazilian Ministry of Health in the period of 1980-2008 looking at sex, age ranges, educational level and exposure category. Patients were divided into three age groups: under 15, from 15 to 49 and over 50 years old. Using a comparative approach, we analyzed data with regard to category of exposure, education (expressed in years of schooling, and sex ratio among younger (15-49 and older adults (over 50 years old. Time series data were log-transformed and normalized, and the temporal trend was evaluated. RESULTS: AIDS incidence is increasing among people over 50 years old in Brazil, with those older than 50 being responsible for 9.64 % of AIDS cases. There was no significant difference between educational level and gender (p = 0.468, but there was a significant difference in exposure category with a lower proportion of injecting drug users amongst the older group. CONCLUSION: Based on this analysis over the last 10 years, the percentage of AIDS cases has increased almost three times among people over 50 years old when compared with the 15-49 year-old group. Our findings suggest that public campaigns have to be specially targeted to the older segment of the population, aiming at heterosexual transmission.

    Full Text Available In the previous study, reports of human immunodeficiency virus (HIV-associated multiple tissue dysfunction syndromes are limit. Now, multiple tissue lesions of one boy with AIDS were analyzed using X-ray, computed tomography (CT and magnetic resonance imaging (MRI. Results showed that obvious brain atrophy and several focus were detected by CT and MRI. Lung lymphoid inflammation and pulmonary lymphoplasia were observed by CT. A swelling with a slight low density in hepatic anterior region of right lobe and a large soft tissue neoplasm in right abdomen were obtained by CT. An obvious damage of intestinal duct and intestinal lymphomas were respectively observed by molybdenum contrast image and CT. X-ray showed a low density of thoracic bone and iliac bone, and irregular shapes of bone joint and epiphysis. Characterizations of HIV-associated multiple organ dysfunction syndromes in the case are benefit to understand features of children with acquired immune deficiency syndrome.

    Full Text Available Munchausen Syndrome By Proxy (MSBP is an extremely complicated diagnosis because of the difficulty in finding the incriminating evidence of its existence and because of the ethical issue it raises for caregivers. Its implications from a medical, psychological and legal point of view raise difficult questions for any professional confronted to it. We present a case of 8 month female infant who was diagnosed to have Hyperinsulinism causing hypoglycemic brain injury and later developing intractable convulsion with head drops, where EEG was suggestive of West Syndrome, was actually a case of Munchausen syndrome by proxy to start with.

    After human immunodeficiency virus(HIV)infection the human body,it mainly involves two meridians of the lung,spleen, but first invasion of lung meridian. Lung is the foundation of the acquired yang,and spleen is the foundation of the acquired yin. Accord-ing to the physiological function of the lung and the characteristics of the HIV virus attacks the human body,clinical manifestations of lung channel appear the earliest,the biggest probability. Spleen is the foundation of the acquired yin,when the lung function impairment or insufficient,pathogenic factors can further and result in spleen channel disease. At the same time,HIV virus invasion of lung and spleen has great specificity,which need to be combined with other comprehensive analysis of the pathogenesis of every period,fully un-derstanding of the pathogenesis of viral features.%人类免疫缺陷病毒(HIV)感染人体后,主要侵犯肺、脾二经,但首犯肺经。肺为后天阳之本,脾为后天阴之本。根据肺的生理功能和 HIV 病毒侵袭人体的特点,肺经的临床表现出现最早,出现的几率也最大。脾为后天阴之本,当肺脏卫外功能减退或不足的时候,病邪即可深入,引起脾经病变。同时 HIV 病毒对肺脾的侵犯具有较大的特异性,需要结合其他各期的病机进行综合分析,完整地认识病毒的发病特性。

    Genetic disorders affecting biogenesis and transport of lysosome-related organelles are heterogeneous diseases frequently associated with albinism. We studied a patient with albinism, neutropenia, immunodeficiency, neurodevelopmental delay, generalized seizures, and impaired hearing but with no mutation in genes so far associated with albinism and immunodeficiency. Whole exome sequencing identified a homozygous mutation in AP3D1 that leads to destabilization of the adaptor protein 3 (AP3) complex. AP3 complex formation and the degranulation defect in patient T cells were restored by retroviral reconstitution. A previously described hypopigmented mouse mutant with an Ap3d1 null mutation (mocha strain) shares the neurologic phenotype with our patient and shows a platelet storage pool deficiency characteristic of Hermansky-Pudlak syndrome (HPS) that was not studied in our patient because of a lack of bleeding. HPS2 caused by mutations in AP3B1A leads to a highly overlapping phenotype without the neurologic symptoms. The AP3 complex exists in a ubiquitous and a neuronal form. AP3D1 codes for the AP3δ subunit of the complex, which is essential for both forms. In contrast, the AP3β3A subunit, affected in HPS2 patients, is substituted by AP3β3B in the neuron-specific heterotetramer. AP3δ deficiency thus causes a severe neurologic disorder with immunodeficiency and albinism that we propose to classify as HPS10. PMID:26744459

    Horner syndrome, a triad of ptosis, anisocoria, and anhidrosis, results from interruption in the oculosympathetic pathway. It is classically described as either congenital or acquired to depict its underlying pathophysiology and requisite work-up. We report a case of a 10-month-old infant presenting with an acute onset of left Horner syndrome secondary to a spontaneous extracranial internal carotid artery dissection. To the best of our knowledge, this is the first case report in the literature of acute onset of acquired infantile Horner syndrome in association with spontaneous carotid artery dissection confirmed with magnetic resonance angiogram.

    Chemotherapeutic agents which affect the integration, stability, or inducibility of the human immunodeficiency virus (HIV) provirus would have considerable value in treating acquired immunodeficiency syndrome. Two nucleoside analogs of cytosine, 5-azacytidine and 5-azadeoxycytidine, which seem to have such value because of their capabilities to affect both the stability and the methylation patterns of the nucleic acids into which they are incorporated, were tested for their ability to inhibit...

    2015-10-01

    This study investigated the social capital of Iranian patients living with acquired immune deficiency syndrome (AIDS) and the associated factors. In a cross-sectional study the Integrated Social Capital Questionnaire was filled by a sequential sample of 300 patients visiting a referral counselling centre in Tehran. The patients' social capital scores were around 50% in the trust, social cohesion, collective action and cooperation and political empowerment domains. The groups and networks membership domain scored the lowest (27.1%). In regression analysis, employment status was significantly associated with groups and networks membership; age, marital status and financial status were associated with collective action and cooperation; period of disease awareness and marital status affected social cohesion and inclusion; and having risky behaviour affected empowerment and political action. Efforts are needed to enhance the social capital of those patients living with AIDS who are younger, unemployed, divorced/widowed, with risky behaviours and shorter disease awareness. PMID:26750165

  3. Chest radiographs in acquired antibody deficiency syndrome with chronic granulomatous inflammation

    Ten cases of acquired antibody deficiency syndrome with chronic granulomatous infection were diagnosed in our hospital during the past 10 years. We were able to perform a retrospective analysis of the initial and follow-up chest radiographs in 8 of these patients. The following pathological findings could be demonstrated: 1. increased bronchovascular markings in the basal lung fields, 2. reticular densities in the middle and basal lung fields, 3. confluent nodular densities of varying size in the periphery of the basal and middle fields, 4. pulmonary infiltrates in the middle and lower lobes, 5. hilar node enlargement of moderate extent. Findings 2, 3 and 5 completely disappeared under steroid therapy whereas 1 showed only partial recovery. If both the radiologic and serologic findings are considered, it is possible to differentiate this disease from sarcoidosis. (orig.)

  6. Primary immunodeficiency syndromes associated with defective DNA double-strand break repair.

    Gennery, A R

    2006-01-01

    Damaging DNA double-strand breaks (DNA-DSBs) following ionizing radiation (IR) exposure, potentially lead to cell death or carcinogenesis. Non-homologous end-joining (NHEJ) is the main repair pathway employed by vertebrate cells to repair such damage. Many repair pathway proteins have been identified. The creation of many diverse lymphocyte receptors to identify potential pathogens has evolved by breaking and randomly re-sorting the gene segments coding for antigen receptors. Subsequent DNA-DSB repair utilizes the NHEJ proteins. Individuals with defective repair pathways are increasingly recognized with radiosensitivity and immunodeficiency. Patients with defects in ataxia-telangiectasia mutated, nibrin, MRE11, Rad50, Artemis, DNA ligase IV and Cernunnos-XRCC4-like factor have been identified. Most exhibit immunodeficiency, with a spectrum of presentation and overlap between conditions. Conventional treatment with immunoglobulin replacement or haematopoietic stem cell transplantation (HSCT) can be effective. A greater understanding of the molecular defect will enable better, tailored therapies to improve survival. PMID:16971555

    Ihara, Akihiro; Suzuki, Nobuaki; Matsushita, Tadashi; Ichinose, Akitada

    2015-07-01

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder similar to inherited von Willebrand disease. We describe a 78-year-old woman with coexistent idiopathic thrombocytopenic purpura (ITP) and AVWS. The patient had once been admitted to our hospital because of cerebral infarction. Her platelet count had been normal at that time. Ten years later, she showed a severe bleeding tendency (platelet count 3.2×10(4)/μl). Analysis of hemostatic parameters showed very low (IgG4) to VWF was detected by enzyme linked immunosorbent assay (ELISA). Factor XIII activity was 42%. Treatment with corticosteroids did not improve the thrombocytopenia, but did correct the bleeding diathesis. Also, VWF: Rco and VIII: C showed normalization. These findings indicated that the patient had ITP associated with AVWS. All reported cases of AVWS associated with systemic lupus erythematosus were cured by appropriate treatment of the underlying autoimmune disease with prednisone or immunosuppression. This bleeding disorder occurs mainly in patients with lymphoproliferative, myeloproliferative, cardiovascular and immunologic disorders, but no patients with ITP have previously been reported. This patient had the rare presentation of AVWS complicated by ITP and factor XIII deficiency. PMID:26256928

    Full Text Available Abstract Introduction Hypereosinophilic syndrome is defined as a prolonged state (more than six months of eosinophilia (greater than 1500 cells/μL, without an apparent etiology and with end-organ damage. Hypereosinophilic syndrome can cause coagulation abnormalities. Among hypereosinophilic syndrome types, the lymphocytic variant (lymphocytic hypereosinophilic syndrome is derived from a monoclonal proliferation of T lymphocytes. Here, we describe the case of a patient with lymphocytic hypereosinophilic syndrome who presented with a coagulation abnormality. To the best of our knowledge, this is the first such report including a detailed clinical picture and temporal cytokine profile. Case presentation A 77-year-old Japanese man presented to our facility with massive hematuria and hypereosinophilia (greater than 2600 cells/μl. His eosinophilia first appeared five years earlier when he developed femoral artery occlusion. He manifested with multiple hematomas and prolonged activated partial thromboplastin time. His IgG4 level was remarkably elevated (greater than 2000 mg/dL. Polymerase chain reaction tests of peripheral blood and bone marrow identified lymphocytic hypereosinophilic syndrome. His prolonged activated partial thromboplastin time was found to be due to acquired hemophilia. Glucocorticoids suppressed both the hypereosinophilia and coagulation abnormality. However, tapering of glucocorticoids led to a relapse of the coagulation abnormality alone, without eosinophilia. Tumor necrosis factor α, interleukin-5, and/or eotaxin-3 may have caused the hypereosinophilia, and interleukin-10 was correlated with the coagulation abnormality. Conclusions To the best of our knowledge, this is the first case in which lymphocytic hypereosinophilic syndrome and IgG4-related disease have overlapped. In addition, our patient is only the second case of hypereosinophilic disease that manifested with acquired hemophilia. Our patient relapsed with the

    Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder that may cause life-threatening hemorrhages in patients with plasma cell dyscrasias (PCDs). Early diagnosis and treatment require a thorough understanding of its underlying pathophysiology. Two patients with IgG MGUS presented with dramatically decreased plasma von Willebrand factor (VWF) and a severe type-1 pattern on multimer analysis. A prompt response to intravenous immunoglobulins (IVIG), but not to VWF/FVIII, was consistent with accelerated immunologic clearance of plasma VWF. Another IgG MGUS patient showed a type-2 pattern and a less pronounced response to IVIG, suggesting that additional mechanism(s) contributed to AVWS evolution. In a patient with Waldenström's macroglobulinemia and severe depletion of plasma VWF, multimer analysis indicated association of the IgM paraprotein with VWF before, but not after plasmapheresis, resulting in destruction of the agarose gel and a characteristically distorted band structure of VWF multimers. A type-2 pattern with highly abnormal VWF triplets and laboratory evidence of excessive fibrinolytic activity suggested that plasmin-mediated VWF degradation contributed to AVWS in a patient with multiple myeloma (MM) and AL amyloidosis. Finally, in a patient with IgG MM, maximally prolonged PFA-100® closure times and a specific defect in ristocetin-induced platelet agglutination, both of which resolved after remission induction, indicated interference of the paraprotein with VWF binding to platelet GPIb. Importantly, in none of the six patients, circulating autoantibodies to VWF were detected by a specific in-house ELISA. In summary, when evaluating PCD patients with severe bleeding symptoms, AVWS due to various pathogenic mechanisms should be considered. PMID:27040683

  13. Correlation of diagnostic imaging and autopsy findings of eight patients with acquired immune deficiency syndrome

    Objective: To investigate the imaging findings with pathologic correlation in patients with acquired immune deficiency syndrome (AIDS). Methods: Imaging findings, autopsy and pathological data were retrospectively analyzed in eight patients with AIDS. Routine CT scanning of different body parts was performed during their hospitalization. CT scanning was performed from the skull to the pelvis immediately following their death. After routine formalin fixing, 7 cadavers were cross sectioned for autopsy in freezing state and 1 for gross autopsy. Tissues were obtained from each sections and organs for pathological examinations. Results: The autopsy data showed parasitic infections (5 cases), bacterial infections (3 cases), fungal infections (2 cases), virus infections (2 cases), lymphoma (1 case) and cerebrovascular diseases (1 case)in eight patients with AIDS. The CT scanning demonstrated symmetrical ground glass liked shadows with pulmonary hilus as the center in 5 cases of pulmonary PCP infection; pulmonary patchy shadows, scattering distribution of nodular shadows, extensive military nodular shadows with even distribution and tuberculous pleurisy; cloudy shadows for 2 cases of fungi infection with multiple foci of chronic inflammation; pulmonary net-like parenchymal changes for 2 cases of pulmonary CMV infection; thickened intestinal wall and narrowed intestinal lumen for 1 case of intestinal tumor; low density shadows of brain tissue for 1 case of CMV encephalitis and MRI findings of high T1 and high T2 signals as well as MRA findings of broken vascular channels in liquefied areas of brain tissues; patchy low density areas inside a cyst of brain for one case of brain toxoplasmosis infection; multiple small patchy low density areas in cerebral basal ganglia for one case of brain cryptococcus infection. Conclusions: In AIDS patients, infection and tumor may occur in various organs resulting in complex symptoms, which makes it more complicated and difficult to make

  14. Clinical aspects of feline immunodeficiency and feline leukemia virus infection.

    Hartmann, Katrin

    2011-10-15

    Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses with a global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FIV can cause an acquired immunodeficiency syndrome that increases the risk of developing opportunistic infections, neurological diseases, and tumors. In most naturally infected cats, however, FIV itself does not cause severe clinical signs, and FIV-infected cats may live many years without any health problems. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma), bone marrow suppression syndromes (mainly anemia) and lead to secondary infectious diseases caused by suppressive effects of the virus on bone marrow and the immune system. Today, FeLV is less important as a deadly infectious agent as in the last 20 years prevalence has been decreasing in most countries. PMID:21807418

    Acquired von Willebrand Syndrome (AVWS) is a rare bleeding disorder associated with hematoproliferative disorders, autoimmune conditions, neoplasia, and cardiovascular disorders that often presents a diagnostic challenge. Monoclonal gammopathy of undetermined significance (MGUS) is one of the most common causes of AVWS that typically presents later in life with mucocutaneous or postsurgical bleeding and multimers consistent with type I or II von Willebrand Disease (VWD). Here we present the c...

  16. CXCL12/CXCR4-Axis Dysfunctions: Markers of the Rare Immunodeficiency Disorder WHIM Syndrome

    Françoise Bachelerie

    2010-01-01

    Full Text Available The WHIM syndrome features susceptibility to human Papillomavirus infection-induced warts and carcinomas, hypogammaglobulinemia, recurrent bacterial infections, B and T-cell lymphopenia, and neutropenia associated with retention of senescent neutrophils in the bone marrow (i.e. myelokathexis. This rare disorder is mostly linked to inherited heterozygous autosomal dominant mutations in the gene encoding CXCR4, a G protein coupled receptor with a unique ligand, the chemokine CXCL12/SDF-1. Some individuals who have full clinical forms of the syndrome carry a wild type CXCR4 gene. In spite of this genetic heterogeneity, leukocytes from WHIM patients share in common dysfunctions of the CXCR4-mediated signaling pathway upon exposure to CXCL12. Dysfunctions are characterized by impaired desensitization and receptor internalization, which are associated with enhanced responses to the chemokine. Our increasing understanding of the mechanisms that account for the aberrant CXCL12/CXCR4-mediated responses is beginning to provide insight into the pathogenesis of the disorder. As a result we can expect to identify markers of the WHIM syndrome, as well as other disorders with WHIM-like features that are associated with dysfunctions of the CXCL12/CXCR4 axis.

  17. Computer simulations of the interaction of human immunodeficiency virus (HIV) aspartic protease with spherical gold nanoparticles: implications in acquired immunodeficiency syndrome (AIDS)

    Whiteley, Chris G.; Lee, Duu-Jong

    2016-09-01

    The interaction of gold nanoparticles (AuNP) with human immune-deficiency virus aspartic protease (HIVPR) is modelled using a regime of molecular dynamics simulations. The simulations of the ‘docking’, first as a rigid-body complex, and eventually through flexible-fit analysis, creates 36 different complexes from four initial orientations of the nanoparticle strategically positioned around the surface of the enzyme. The structural deviations of the enzymes from the initial x-ray crystal structure during each docking simulation are assessed by comparative analysis of secondary structural elements, root mean square deviations, B-factors, interactive bonding energies, dihedral angles, radius of gyration (R g), circular dichroism (CD), volume occupied by C α , electrostatic potentials, solvation energies and hydrophobicities. Normalisation of the data narrows the selection from the initial 36 to one ‘final’ probable structure. It is concluded that, after computer simulations on each of the 36 initial complexes incorporating the 12 different biophysical techniques, the top five complexes are the same no matter which technique is explored. The significance of the present work is an expansion of an earlier study on the molecular dynamic simulation for the interaction of HIVPR with silver nanoparticles. This work is supported by experimental evidence since the initial ‘orientation’ of the AgNP with the enzyme is the same as the ‘final’ AuNP-HIVPR complex generated in the present study. The findings will provide insight into the forces of the binding of the HIVPR to AuNP. It is anticipated that the protocol developed in this study will act as a standard process for the interaction of any nanoparticle with any biomedical target.

    Full Text Available Background : In South Africa where many patients are immunocompromised as a result of the AIDS pandemic, opportunistic fungal infections such as candidiasis caused mainly by Candida albicans are common. Arctotis arctotoides and Gasteria bicolor are two plants which are frequently and commonly used in traditional medicine in the treatment of HIV patients. Aim: The aim of this study was to investigate the antifungal activity of A. arctotoides and G. bicolor against opportunistic fungi common in HIV/AIDS patients. Materials and Methods: The agar diffusion and micro-dilution methods were used to determine the antifungal activities of the medicinal plant extracts against 10 opportunistic fungi. Results: All the hexane and acetone extracts were active against at least one of the fungi with zones of inhibition varying from 8 to 32 mm, while none of the aqueous extracts was active against any of the fungi. The inhibitory activity of the active extracts, based on the overall mean inhibition diameters, was in the order: A. arctotoides (hexane > A. arctotoides (acetone > G. bicolor (hexane > G. bicolor (acetone. The most susceptible fungi, based on the overall mean diameter of growth inhibition, were Candida glabrata, C. krusei, and Microsporum canis, while Cyptococcus neoformans, Trycophyton tonsurans, and Microsporum gypseum were not susceptible to any of the extracts even at 5 mg/ml which was the highest concentration used. Conclusion: This study validates the use of these plants in traditional medicine in the treatment of secondary fungal infections in HIV/AIDS patients.

    Full Text Available This study was done to determine the occurrence of mycobacteria in the bloodstreams of patients with fever and advanced AIDS in a Brazilian hospital. We also verified the capability of an automated method for recovering these bacteria. During a period of 19 months, 254 patients with AIDS were evaluated. Blood cultures were generally submitted in pairs and drawn separately. Blood cultures were processed by the BACTEC 460TB System (Becton Dickinson Microbiology Systems, Sparks, MD, using the Bactec 13A media (Becton Dickinson Microbiology Systems, Sparks, MD. Of the 530 vials submitted, 77 (14.5% from 41 (16% patients were positive. Mycobacterium avium complex was recovered from 45 (58.4% of the 77 positive vials, corresponding to 22 (53.6% patients with positive blood cultures. The average time to detect Mycobacterium avium complex was 15 days. Mycobacterium tuberculosis was recovered from 26 (33.8% of the 77 positive vials, corresponding to 15 (36.6% patients with positive blood cultures, with an average detection time of 24 days. Other species of mycobacteria were recovered from 6 (7.8% of the 77 vials, corresponding to 4 (9.8% patients. M.avium complex was fairly prevalent (8.7% in severely ill patients with AIDS in our hospital. M. tuberculosis was also an important (6.0% agent of systemic bacterial infections in these patients. The rapid diagnosis of mycobacteremia was possible with the implementation of this automated technology.

  2. Focal lung uptake of gallium-67 in patients with acquired immunodeficiency syndrome secondary to pneumocystis carinii pneumonia

    It is generally accepted that the lung uptake of 67Ga in patients with pneumocystis carinii pneumonia (PCP) is diffuse and bilateral. Three cases of focal lung uptake of 67Ga in AIDS patients with PCP but without other opportunistic infections are described. While focal lung uptake is characteristic of opportunistic infections other than PCP, we wish to emphasize that focal uptake of gallium in the chest does not rule out PCP and may represent its earliest stage of presentation.

  3. Public perceptions about HIV/AIDS and discriminatory attitudes toward people living with acquired immunodeficiency syndrome in Iran.

    Masoudnia, Ebrahim

    2015-01-01

    Negative and discriminatory attitudes towards people living with HIV/AIDS (PLWHA) are one of the biggest experienced challenges by people suffering from HIV, and these attitudes have been regarded as a serious threat to the fundamental rights of all infected people who are affected or associated with this disease in Iran. This study aimed to determine the relationship between public perception about HIV/AIDS and discriminatory attitudes toward PLWHA . The present study was conducted using a descriptive and survey design. Data were collected from 450 patients (236 male and 214 female) in Tehran and Yazd cities. The research instruments were modified HIV-related knowledge/attitude and perception questions about PLWHA, and discriminatory attitudes toward PLWHA. The results showed that prevalence of discriminatory attitudes toward PLWHA in the studied population was 60.0%. There was a significant negative correlation between citizens' awareness about HIV/AIDS, HIV-related attitudes, negative perception toward people with HIV/AIDS symptoms and their discriminatory attitudes toward PLWHA (p < .01). The hierarchical multiple regression analysis showed that components of public perception about HIV/AIDS explained for 23.7% of the variance of discriminatory attitudes toward PLWHA. Negative public perceptions about HIV/AIDS in Iran associated with discriminatory attitudes toward PLWHA and cultural beliefs in Iran tend to stigmatize and discriminate against the LWHA.

    We report on 11 patients with 8 independent families (3 pairs of sibs) with a complex clinical pattern including microcephaly, peculiar {open_quotes}bird-like{close_quotes} face, growth retardation, and, in some cases, mild-to-moderate mental deficiency. Most of the patients have recurring respiratory tract infections. One girl has developed B-cell lymphoma. A detailed anthropometric study of 15 physical parameters, including 3 cephalic traits, was performed. It was possible to study the chromosomes of PHA-stimulated lymphocytes in all of the patients. We found structural aberrations with multiple rearrangements, preferentially involving chromosomes 7 and 14 in a proportion of metaphases in all individuals. Profound humoral and cellular immune defects were observed. Serum AFP levels were within normal range. Radioresistant DNA synthesis was strongly increased in all 8 patients who were hitherto studied in this respect. Our patients fulfill the criteria of the Nijmegen breakage syndrome, which belongs to the growing category of ataxia telangiectasia-related genetic disorders. In light of the increased predisposition to malignancy in this syndrome, an accurate diagnosis is important for the patient. 27 refs., 5 figs., 4 tabs.

    Full Text Available We present a case of pancytopenia and cutaneous cryptococcosis in a young girl with no complaints of fever, headache and vomiting. Fine-needle aspiration cytology and further investigation for pancytopenia revealed presence of Cryptococcus in skin and bone marrow aspirates. Fungal cultures of the skin aspirates, blood and bone marrow confirmed cryptococcal infection. Counselling and human immunodeficiency virus (HIV test revealed the status of the patient to be retropositive. Although meningitis is the commonest manifestation of cryptococcosis among HIV-infected patients, rare cutaneous manifestation with pancytopenia but with no meningeal signs indicate the HIV status in an endemic area of penicilliosis, Manipur.

    Poliovirus transmission has been eliminated in most of the world through the use of inactivated poliovirus vaccine (IPV) and live, attenuated oral poliovirus vaccine (OPV). In the United States, use of OPV was discontinued by the year 2000 because of the potential for vaccine-associated paralytic polio (VAPP); an average of eight cases were reported each year in the United States during 1980-2000. Polio eradication efforts in other parts of the world continue to rely on OPV to take advantage of transmission of poliovirus vaccine strains to unvaccinated persons in the population, lower cost, and ease of administration. In 2013, an infant aged 7 months who recently immigrated to the United States from India was referred to a hospital in San Antonio, Texas. The infant had fever, an enlarging skin lesion in the deltoid region with axillary lymphadenopathy, decreased activity, and inability to bear weight on the left leg, progressing to paralysis of the left leg over a 6-week period. Recognition of lymphopenia on complete blood count led to immune evaluation, which revealed the presence of severe combined immunodeficiency syndrome (SCIDS), an inherited disorder. A history of OPV and bacille Calmette-Guérin (BCG) vaccination in India led to the diagnoses of VAPP and BCG-osis, which were confirmed microbiologically. This report demonstrates the importance of obtaining a comprehensive clinical history in a child who has recently immigrated to the United States, with recognition that differing vaccine practices in other countries might require additional consideration of potential etiologies.

    The spine is the most common site of skeletal involvement in tuberculosis. The radiologic features are reportedly characterized by destruction of the vertebral body, subligamentous extension or subchondral penetration, frequent paravertebral abscess formation and late involvement of the disk space. We experienced a case of a 25-year-old male who was a human immunodeficiency virus carrier without antiretroviral therapy. Incidental findings on abdominal computed tomography included multiple well-demarcated and ovoid osteolytic lesions with hyperdense rims disseminated in the thoracic, lumbar, and sacrum vertebrae, as well as in both ilii. On the lumbar spine magnetic resonance imaging, multiple small round lesions of isointense signal intensity with peripheral hyperintense rims were found on both T1- and T2-weighted imaging. The lesions had peripheral rim enhancement on gadolinium-enhanced T1-weighted imaging. Based on our experience, this rare image finding is one of the manifestations of disseminated tuberculosis.

    2015-01-01

    Full Text Available Introduction: Ondine’s Curse is a catastrophic but rare condition in adults. It is referred to as a congenital or acquired condition, in which the patient cannot breathe automatically while asleep. Acquired causes of this disease can be any cause affecting the ventrolateral part of the medulla, which is considered to be the breathing center in humans.    Case Report:   A 51-year-old woman, with ataxia and the symptoms and signs of rising Intra-Cranial Pressure, who underwent ventriculoperitoneal shunting and removal of tumour, developed episodic apnea during sleep after surgery and hypercapnia when awake. In her post-operative CT scan, some fine spots of hypodensity in the left lateral part of the medulla were observed. She was managed pharmacologically and underwent tracheotomy. After 50 days, she was discharged from the hospital when she was able to breathe normally.   Conclusion:  Having experience with this condition after resection of a fourth ventricle tumor, it was found that Ondine’s Curse can be considered as one of the complications of  posterior fossa surgery and is curable by proper management.

    A 73-year-old heterosexual man developed a high-grade non-Hodgkin's lymphoma at the site of an ileostomy only 2 years after proctectomy for undetermined colitis not cured by previous colectomy. In fact, the early occurrence of this usually very late and rare complication of ileostomy was probably favored by the simultaneous presence of acquired immune deficiency syndrome (AIDS) due to repeated blood transfusions for refractory anemia with excess blasts. The intestinal location of the tumor, its high-grade malignancy and B-cell origin are all features of AIDS-related non-Hodgkin's lymphoma. This case report seems to be one of the rarely identified examples of the cooperation between general predisposing factors and local irritating agents at the origin of a malignant tumor.

    AIMS: Impaired repolarization in cardiac myocytes can lead to long QT syndrome (LQTS), with delayed repolarization and increased susceptibility to Torsades de Pointes (TdP) arrhythmias. Current pharmacological treatment of LQTS is often inadequate. This study sought to evaluate the antiarrhythmic...... effect of a novel compound (NS1643) that activates the rapid delayed-rectifier K+ current, I(Kr), in two rabbit models of acquired LQTS. METHODS AND RESULTS: We used two clinically relevant in vivo rabbit models of TdP in which we infused NS1643 or vehicle: (i) three-week atrioventricular block with...... ventricular bradypacing; (ii) dofetilide-induced I(Kr) inhibition in methoxamine-sensitized rabbits. In addition, we studied effects on ionic currents in cardiomyocytes with I(Kr) suppressed by bradycardia remodelling or dofetilide exposure. Bradypaced rabbits developed QT interval prolongation, spontaneous...

  14. Wernicke's Encephalopathy: An Unusual Consequence of the Acquired Immune Deficiency Syndrome-Case Report and Literature Review.

    Larsen, Timothy R; Dragu, Dritan; Williams, Michael

    2013-01-01

    Introduction. Wernicke's encephalopathy is a well-described syndrome characterized by the classic triad of confusion, ataxia, and ophthalmoplegia. Wernicke's encephalopathy results from thiamine (vitamin B1) deficiency. Common causes include alcoholism and gastric disorders. Wernicke's has been described in patients with acquired immune deficiency syndrome (AIDS); however, given these patients' immunosuppressed state, the diagnosis of Wernicke's encephalopathy is not apparent. Case Presentation. A 31-year-old previously healthy male presented to the ER complaining of progressive dyspnea. Workup revealed HIV/AIDS and PCP pneumonia. He was treated and improved. On day 14 he became confused and developed nystagmus and ataxia. Considering his immunocompromised state, infectious and neoplastic etiologies topped the differential diagnosis. CT head was negative. Lumbar puncture was unremarkable. Brain MRI revealed increased T2 signal in the medial thalamus bilaterally. Intravenous thiamine was administered resulting in resolution of symptoms. Discussion. The classic triad of Wernicke's encephalopathy occurs in 10% of cases. When immunosuppressed patients develop acute neurologic symptoms infectious or neoplastic etiologies must be excluded. However, given the relative safety of thiamine supplementation, there should be a low threshold for initiating therapy in order to reverse the symptoms and prevent progression to Korsakoff dementia, which is permanent.

    Full Text Available The X-linked lymphoproliferative syndrome (XLP is a rare, inherited immunodeficiency characterized by recurrent episodes of hemophagocytic lymphohistiocytosis, hypogammaglobulinemia, and/or lymphomas. Recently, X-linked inhibitor of apoptosis (XIAP/BIRC4 gene defects, in families with XLP but without SH2D1A gene defects, has been defined. The distinction from primary immunodeficiencies with a defined genetic cause is mandatory. A six-year-old male patient was admitted with the complaints of persistent general lymphadenopathy, for two years had fever, bilateral cervical multiple microlymphadenopathy, hepatic/splenic enlargement with laboratory findings as decreased serum immunoglobulins, negative EBV VCA IgM (viral capsid antigen and anti-EBV EA (antibody to early D antigen, positive EBV VCA IgG (viral capsid antigen and EBV EBNA (antibody to nuclear antigen. SH2D1A gene analysis was negative. XIAP/BIRC4 sequencing revealed two novel single nucleotide variants (exon 7, 1978G > A, and 1996T > A in the 3′UTR of the gene in both patient and mother which were not disease causing. XIAP protein expression was found to be normal. The clinical and laboratory resemblance, no gene mutations, and normal XIAP protein expression led us to think that there may be another responsible gene for XLP. The patient will to be followed up as CVID until he presents new diagnostic signs or until the identification of a new gene.

    Human immunodeficiency virus (HIV)–associated pulmonary arterial hypertension (PAH) is a devastating, noninfectious complication of acquired immune deficiency syndrome, and the majority of HIV-PAH cases occur in individuals with a history of intravenous drug use (IVDU). However, although HIV-1 and IVDU have been associated with PAH independently or in combination, the pathogenesis of the disproportionate presence of HIV-PAH in association with IVDU has yet to be characterized. The objective o...

    2007-08-01

    Pulmonary complications in children infected by human immunodeficiency virus (HIV) are common and may be the first manifestation of acquired immunodeficiency syndrome (AIDS). The aim of our study was to review pulmonary diseases and complications in pediatric patients with HIV infection in a large tertiary hospital in Santiago, Chile. We performed a retrospective, descriptive analysis of 17 patients with HIV infection controlled at the Hospital Dr. Sótero del Rio. Respiratory complications/diseases were: overall pneumonia (n: 14), recurrent pneumonia (n: 10), citomegalovirus associated pneumonia (n: 4), Pneumocystis jiroveci associated pneumonia (n: 1) pulmonary tuberculosis (n: 1), lymphoid interstitial pneumonia (n: 3) and chronic pulmonary disease (n: 7). Microorganisms isolated were mostly atypical and frequently associated with severe and chronic pulmonary damage. A high degree of suspicion is required to detect atypical microorganisms promptly, in order to rapidly implement pathogen targeted therapy that could potentially decrease the possibility of sequelae.

  20. Rapidly progressive periodontal disease associated with human immunodeficiency virus

    Severe periodontal inflammation with generalized dental plaque accumulation, spontaneous and severe gingival bleeding, fungal infection, and inter dental papillae necrosis are presented in a patient infected with human immunodeficiency virus (HIV). Bite-wing radiographs revealed a generalized horizontal alveolar bone loss of 7-8 millimetres in both arches. Erythematous patches were noted on the gingival mucosa in both jaws. DNA testing was performed to identify the periodontopathogens. The patient had no signs or symptoms of acquired immunodeficiency syndrome. This case-report presents the massive periodontal destruction that occurred in a patient infected with HIV. Therefore, it is highly recommended that patients infected with HIV should be regularly monitored to aid in early detection and to provide proper management of periodontal inflammatory conditions to minimize its destruction.

  1. Common variable immunodeficiency: etiological and treatment issues.

    Deane, Sean; Selmi, Carlo; Naguwa, Stanley M; Teuber, Suzanne S; Gershwin, M Eric

    2009-01-01

    One of the great advances in clinical medicine was the recognition of the pleomorphism of the immune response and the multiple afferent and efferent limbs of antigen processing and responsiveness. A significant contribution to this understanding was derived from studies of human immunodeficiency states, including both inherited and acquired syndromes. Amongst these syndromes, one of the most common, and least understood, is common variable immune deficiency (CVID). CVID is a syndrome that leads to a reduction in serum immunoglobulins and complications including recurrent infections. Management includes immunoglobulin replacement therapy; however, patients with CVID are at risk for complications of exogenous immunoglobulin administration as well as CVID-associated diseases such as autoimmune processes and malignancies. To assess the current state of knowledge in the field, we performed a literature review of a total of 753 publications covering the period of 1968 until 2008. From this list, 189 publications were selected for discussion. In this review, we demonstrate that while the molecular basis of CVID in many cases remains incompletely understood, significant strides have been made and it is now clear that there is involvement of several pathways of immune activation, with contributions from both T and B cells. Furthermore, despite the current gaps in our knowledge of the molecular pathogenesis of the syndrome, there have been dramatic advances in management that have led to improved survival and significantly reduced morbidity in affected patients.

  12. Tissue tropism of simian immunodeficiency virus in rhesus monkeys

    Simian immunodeficiency virus (SIV) is a T-lymphotropic lentivirus that is genetically, immunologically, and morphologically related to the human immunodeficiency viruses type 1 and 2 (HIV-1, HIV-2). In rhesus monkeys, SIV induces a progressively fatal immunodeficiency syndrome strikingly similar to human acquired immunodeficiency syndrome (AIDS). The tissue and cellular tropism of SIV was determined by immunocytochemistry and in situ hybridization using a 3.48 kilobase SIV envelope gene probe labeled with biotin, 35S, or 3H. Probes labeled with 35S nonspecifically bound to tissue eosinophils and produced poor signal resolution compared to tritium labeled probes. Biotin labeled probes did not detect SIV under similar hybridization conditions. Formalin-fixed, paraffin-embedded tissues produced strong hybridization signal with superior morphology compared to frozen tissues. Gastrointestinal, respiratory, and lymphoid tissues most frequently contained SIV RNA. The distribution of SIV did not correlate with sex, or viral inoculum, but was most extensive in animals with SIV induced granulomatous encephalitis. SIV was most frequently observed in lymphocytes and macrophages. In the brain focal granulomas were composed almost entirely of EBM11+, lysozyme+, macrophages which contained large amounts of SIV RNA and p27 core protein detected by the monoclonal antibody R1C7. Cells away from granulomas in the brain parenchyma and around blood vessels contained virus and were compatible with oligodendrocytes and astrocytes. Lymph nodes in follicular hyperplasia contained small numbers of SIV positive cells compatible with lymphocytes in the paracortex and mantle zones as well as in cells of the germinal center. Lymph nodes in various stages of follicular depletion with expanded paracortices contained large numbers of cells with SIV RNA in lymphocytes and macrophages

  13. A Case of Fatal Congenital Human Immunodeficiency Virus Infection

    Halil Uğur Hatipoğlu

    2016-06-01

    Full Text Available Acquired immune deficiency syndrome is a clinical condition caused by human immunodeficiency virus (HIV which can be transmitted either vertically or horizontally. More than 90% of children living with HIV in developing countries have been infected through mother to child transmission during pregnancy, around the time of birth, or through breastfeeding. In order to reduce the number of infected children, increasing emphasis should be placed on preventing mother to child transmission programs with the use of antiretroviral medications in the pregnant woman during pregnancy and at delivery and, starting immediately after birth for the exposed infant. Here, we present the case of a 60-day-old infant heavily immunocompromised due to an extremely high viral burden of HIV, which was acquired perinatally from an undiagnosed and untreated mother, leading to severe bronchopneumonia, sepsis, septic shock and death.

  14. Impaired expression of mitochondrial and adipogenic genes in adipose tissue from a patient with acquired partial lipodystrophy (Barraquer-Simons syndrome: a case report

    2008-08-01

    Full Text Available Abstract Introduction Acquired partial lipodystrophy or Barraquer-Simons syndrome is a rare form of progressive lipodystrophy. The etiopathogenesis of adipose tissue atrophy in these patients is unknown. Case presentation This is a case report of a 44-year-old woman with acquired partial lipodystrophy. To obtain insight into the molecular basis of lipoatrophy in acquired partial lipodystrophy, we examined gene expression in adipose tissue from this patient newly diagnosed with acquired partial lipodystrophy. A biopsy of subcutaneous adipose tissue was obtained from the patient, and DNA and RNA were extracted in order to evaluate mitochondrial DNA abundance and mRNA expression levels. Conclusion The expression of marker genes of adipogenesis and adipocyte metabolism, including the master regulator PPARγ, was down-regulated in subcutaneous adipose tissue from this patient. Adiponectin mRNA expression was also reduced but leptin mRNA levels were unaltered. Markers of local inflammatory status were unaltered. Expression of genes related to mitochondrial function was reduced despite unaltered levels of mitochondrial DNA. It is concluded that adipogenic and mitochondrial gene expression is impaired in adipose tissue in this patient with acquired partial lipodystrophy.

  15. Approach to a child with primary immunodeficiency

    Özge Yılmaz

    2010-09-01

    Full Text Available Primary immunodeficiencies are clinically and epidemiologically important, despite their low prevalence, due to the associated risk of high morbidity and mortality. Most commonly encountered primary immunodeficiencies include humoral immune system deficiencies, cellular immune system defects, combined immunodeficiencies, phagocyte system defects, complement system defects. Classical clinical findings of immunodeficiencies include recurrent, severe infections which do not respond to treatment or which progress with complications as well as tendency to develop infections with low virulence microorganisms. Moreover, they may present with autoimmunity, autoinflammatory or hemaphagocytic syndromes. Congenital diseases usually start in early childhood and lead to morbidity and mortality. Therefore, early diagnosis may be life saving and allow increasing quality of life, genetic counseling or prenatal diagnosis. Considering primary immunodeficiencies more frequently in differential diagnosis and early immunological evaluation would lead to early diagnosis of these patients and allow them to reach early treatment or preventive measures.

  16. Common Variable Immunodeficiency and Peripheral Lung Nodule

    Miguel Ángel Núñez

    2008-01-01

    Full Text Available Cryptococcus neoformans is an encapsulated yeast first isolated by Busse in 1894 from the tibia of a 31-year-old woman [1]. Lungs are considered the initial site of almost all cryptoccocal infections, and the second clinically more relevant after central nervous system. The pattern of pulmonary disease is extremely variable, ranging from asymptomatic saprophytic airway colonization to acute respiratory distress syndrome, mainly observed in immunocompromised patients [2].Exposition to Cryptococcus is virtually universal, and usually occurs during childhood. It is thought that humans become infected after inhalation of the fungus. Afterwards, it causes a little focal pneumonitis which may or may not becomes symptomatic, mainly depending on the immune status of the host. In this initial phase of infection, animal models have demonstrated that alveolar macrophages, natural killer cells and helper T-cells are the most important host defence mechanisms against the fungus. In fact, the most serious infections usually occur in subjects with conditions associated with defective cell-mediated immunity, such as acquired immunodeficiency syndrome (AIDS, cirrhosis, renal failure, sarcoidosis, chronic lung disease, diabetes, stem-cell and solid organ transplantation, malignancies, and treatment with long-term corticosteroids of tumour necrosis factor (TNF antagonists. However, patients with immunoglobulin deficiency are less prone to develop this fungal infection [3].

    2006-01-01

    Since the original description of X-linked agammaglobulinemia in 1952, the number of independent primary immunodeficiency diseases (PIDs) has expanded to more than 100 entities. By definition, a PID is a genetically determined disorder resulting in enhanced susceptibility to infectious disease. Despite the heritable nature of these diseases, some PIDs are clinically manifested only after prerequisite environmental exposures but they often have associated malignant, allergic, or autoimmune manifestations. PIDs must be distinguished from secondary or acquired immunodeficiencies, which are far more common. In this review, we will place these immunodeficiencies in the context of both clinical and laboratory presentations as well as highlight the known genetic basis. PMID:17162365

  8. A conceptual approach to immunodeficiency.

    Bardana, E J

    1981-09-01

    Immunodeficiency represents a congenital or acquired aberration of immune function which is commonly associated with autoimmunity and neoplasia as a potential triad of biologic sequelae. Irrespective of the initial focal point in the triad, the natural evolution of the condition is frequently associated with the other two. This conceptualization should increase the clinician's ability in a more understanding approach to the evaluation and care of immunocompromised patients. PMID:7026918

    Objective To investigate the situation of mother to child transmission of HIV after mothers acquired HIV prenatally or before pregnancy and the related factors. Methods Two hundred and seventy-seven mothers who acquired HIV prenatally or before pregnancy and their 322children from Yi-ning city of Xinjiang Uygur autonomous region and some counties of central China were enrolled in this study from January 2000 to December 2009.Subtypes of HIV were determined by detection of Gag sequence,the rate of HIV transmission from mother to child was calculated and its related factors were analyzed by Chi-square test and Logistic regression analysis. Results The HIV subtype of all mothers who were infected through blood (n=174) was B'.The major subtype of mothers who were infected via sexuality (n =58) was recombined subtype CRF01-BC (n=35) and CRF-AE (n=20),accounting for 60.3% and 34.5%,respectively,and only 3 mothers with B'subtype (5.2%).Twelve infants died before HIV detection,and 108 infants out of the rest 310infants were found to be HIV positive, giving the HIV mother-to-child transmission rate of 34.8% (95% CI:29.5%-40.1%).The infection rate of bottle feeding infants was lower than that of breastfeeding infants [12.5% (6/48) vs 38.9% (102/262),x2 =12.484,P=0.000].The infection rate of the infants whose mothers' HIV infection <7 years was lower than that of the infants whose mothers' HIV infection ≥7 years [28.8% (46/160) vs 54.2% (32/59),x2 =12.211,P=0.000].Multi-factor Logistic analysis showed that the duration of maternal HIV infection (OR =1.342,95% CI:1.189-1.515,P=0.000) and duration of breastfeeding (OR =1.137,95% CI:1.053-1.227,P=0.001) were risk factors of HIV vertical transmission. Conclusions The HIV subtypes might be associated with transmission route.Formula feeding could decrease the vertical transmission rate of HIV,while long duration of maternal HIV infection and breastfeeding might increase the vertical transmission rate

  10. Detection of anti-Chlamydia trachomatis Antibodies in Patients with Acquired Immune Deficiency Syndrome in Abuja, Nigeria

    Izebe, K. S.

    2008-01-01

    Full Text Available Chlamydia trachomatis (CT infections are among the sexually transmitted diseases known to increase the risk for human immunodeficiency virus infection. Serum samples from 34 consenting AIDS patients which attended the Government-approved Antiretroviral Treatment (ART Facility at the National Institute for Pharmaceutical Research and Development (NIPRD, Abuja between April 2005 and March 2006 were screened by enzyme immunoassay (EIA for the presence of anti-CT antibodies using ImmunoComb® Chlamydia Bivalent IgG Test kit (Orgenics, Israel. Anti-CT antibodies were detected in ten (29.4% of the thirty-four patients tested. The detection rate was higher among the females (33.3% than the males (23.1%. Patients of the age group 31-45 years had the highest detection of anti-C. trachomatis antibodies, followed by those of age group 16-30 years. The result of the present study suggests the presence of anti-CT antibodies in AIDS patients, and reinforces the need for routine screening for anti-CT antibodies as a necessary intervention to reduce the burden of chlamydial diseases and to reduce the risk of HIV and its spread in Nigeria. The outcome of this study also provides justification for the possible inclusion of anti-chlamydial agents in the National AIDS Management Plan to treat associated C. trachomatis infections.

    1998-01-01

    Within the last three years, major progress in the understanding of acquired immune deficiency syndrome pathogenesis has been achieved. The discovery that human immunodeficiency virus (HIV), in addition to the CD4 receptor, requires the presence of a coreceptor in order to infect cells has led to a...... series of breakthroughs in HIV research and knowledge. These include an increased understanding of viral entry, a connection of viral phenotype to specific coreceptor use, and an unequivocal linkage of a single human gene to host susceptibility. All in all these achievements provide a number of promising...... new strategies for combating HIV....

    Plasmablastic lymphoma is a rare and aggressive subtype of diffuse large B cell non-Hodgkin lymphoma, originally described in the oral cavity of male adults with acquired immune deficiency syndrome. It is composed of neoplastic ceils which resemble immunoblasts but present immunophenotype distinctive of plasma cell and Epstein-Barr virus latent infection. In children, it is an even rarer disease. We present a case of oral plasmablastic lymphoma in a vertically transmitted human immunodeficiency virus-positive five-year-old child. PMID:27079412

    Nowadays, the human immunodeficiency virus infection (HIV) is a chronic disease. In the frequent clinical situations with fever, lymph nodes and loss weight it is necessary to determine their etiology, for establishing a specific treatment. Gastrointestinal opportunistic infections or gastric lymphomatous or sarcomatous process, which can accumulate Ga67, may be present in the patient with acquired immunodeficiency syndrome. We report 2 cases with gastric uptake in which endoscopy and biopsy was obtained. In the first one, with previous treatment with omeprazol and almalgate for gastroesophagic reflux, endoscopy and biopsy were normal and in the second patient an Helicobacter pylori infection was diagnosed. We think that gastric uptake of Ga67 in HIV patients, must indicate to the clinician to rule out associated pathologies. PMID:14974895

  14. The Biology of Kaposi's Sarcoma-Associated Herpesvirus and the Infection of Human Immunodeficiency Virus

    2008-01-01

    Kaposi sarcoma-associated herpesvirus (KSHV),also known as human herpesvirus 8 (HHV-8),is discovered in 1994 from Kaposi's sarcoma (KS) lesion of an acquired immunodeficiency syndrome (AIDS)patient.In addition to its association with KS,KSHV has also been implicated as the causative agent of two other AIDS-associated malignancies:primary effusion lymphoma (PEL) and multicentric Castleman's disease (MCD).KSHV is a complex DNA virus that not only has the ability to promote cellular growth and survival for tumor development,but also can provoke deregulated angiogenesis,inflammation,and modulate the patient's immune system in favor of tumor growth.As KSHV is a necessary but not sufficient etiological factor for KS,human immunodeficiency virus (HIV) is a very important cofactor.Here we review the basic information about the biology of KSHV,development of pathogenesis and interaction between KSHV and HIV.

    2015-06-01

    As Acquired Immunodeficiency Disease (AIDS) turns thirty-years old, much progress has been made. 56,000 new cases of the Human Immunodeficiency Virus (HIV) infection are expected in Americans this year. At least half or more will be in African Americans. Reports of the association between syphilis and HIV infection are well documented. We present a case of bilateral optic neuritis and panuveitis as the initial presentation in a previously undiagnosed patient with human immunodeficiency virus (HIV) and syphilis. PMID:27269502

  16. Genetic variability in human immunodeficiency viruses.

    Alizon, M; Montagnier, L

    1987-01-01

    The genetic polymorphism of the human immunodeficiency virus (HIV) has been established. In addition to the nucleic acid variations responsible for the restriction map polymorphism, isolates of HIV differ significantly at the protein level, especially in the envelope, in terms of amino acid substitutions and reciprocal insertions-deletions. In this investigation, molecular cloning and nucleotide sequencing of the genomes of 2 HIV isolates obtained from patients in Zaire were carried out. The 1st isolate was recovered in 1983 from a 24-year-old woman with acquired immunodeficiency syndrome (AIDS); the 2nd was isolated in 1985 from a 7-year-old boy with AIDS-related complex (ARC). The genetic organization of these isolates was identical to that found in other HIV isolates from the US and Europe, particularly in terms of the conservation of the central region located between the pol and env genes composed of a series of overlapping open reading frames. There were, however, substantial differences in the primary structure of the viral proteins, with env being more variable than the gag and pol genes. Alignment of the envelopes revealed hypervariable domains with a great number of mutations and reciprocal insertions and deletions. Overall, this analysis suggests that the African and American HIV infections have a common origin given their identical genetic organization. The sequence variability reflects a divergent evolutionary process, and the fact that the 2 Zairian isolates were more divergent than American isolates studied by others indicates a longer evolution of HIV in Africa. An essential research goal is to identify the HIV envelope domains responsible for the virus-cellular surface antigen interaction since an immune response against these epitopes could elicit neutralizing antibodies for use in a vaccine.

    Davis, M.G.; Kenney, S.C.; Kamine, J.; Pagano, J.S.; Huang, E.S.

    1987-12-01

    Almost all homosexual patients with acquired immunodeficiency syndrome are also actively infected with human cytomegalovirus (HCMV). The authors have hypothesized that an interaction between HCMV and human immunodeficiency virus (HIV), the agent that causes acquired immunodeficiency syndrome, may exist at a molecular level and contribute to the manifestations of HIV infection. In this report, they demonstrate that the immediate-early gene region of HCMV, in particular immediate-early region 2, trans-activates the expression of the bacterial gene chloramphenicol acetyltransferase that is fused to the HIV long terminal repeat and carried by plasmid pHIV-CAT. The HCMV immediate-early trans-activator increases the level of mRNA from the plamid pHIV-CAT. The sequences of HIV that are responsive to trans-activation by the HDMV immediate-early region are distinct from HIV sequences that are required for response to the HIV tat. The stimulation of HIV gene expression by HDMV gene functions could enhance the consequences of HIV infection in persons with previous or concurrent HCMV infection.

    2013-01-01

    Full Text Available Since the discovery of acquired immuno deficiency syndrome (AIDS in late1980s, the spread of human immunodeficiency virus (HIV has reached pandemic proportions, representing a global developmental and public health threat. Finding of a safe, globally effective and affordable HIV vaccine offers the best hope for the future control of the disease pandemic. Significant progress has been made over the past years in the areas of basic virology, immunology, and pathogenesis of HIV/AIDS and the development of anti-retroviral drugs. However, the search for an HIV vaccine faces formidable scientific challenges related to the high genetic variability of the virus, the lack of immune correlates of protection, limitations with the existing animal models and logistical problems associated with the conduct of multiple clinical trials. Most of the vaccine approaches developed so far aim at inducing cell-mediated immune responses. Multiple vaccine concepts and vaccination strategies have been tested, including DNA vaccines, subunit vaccines, live vectored recombinant vaccines, various prime-boost vaccine combinations and vaccine based on broadly neutralizing human anti-HIV Antibody 2G12. This article reviews the state of the art in HIV vaccine research, summarizes the results obtained so far and discusses the challenges to be met in the development of a successful HIV vaccine.

  2. Restless led syndrome model Drosophila melanogaster show successful olfactory learning and 1-day retention of the acquired memory

    Mika F. Asaba

    2013-09-01

    Full Text Available Restless Legs Syndrome (RLS is a prevalent but poorly understood disorder that ischaracterized by uncontrollable movements during sleep, resulting in sleep disturbance.Olfactory memory in Drosophila melanogaster has proven to be a useful tool for the study ofcognitive deficits caused by sleep disturbances, such as those seen in RLS. A recently generatedDrosophila model of RLS exhibited disturbed sleep patterns similar to those seen in humans withRLS. This research seeks to improve understanding of the relationship between cognitivefunctioning and sleep disturbances in a new model for RLS. Here, we tested learning andmemory in wild type and dBTBD9 mutant flies by Pavlovian olfactory conditioning, duringwhich a shock was paired with one of two odors. Flies were then placed in a T-maze with oneodor on either side, and successful associative learning was recorded when the flies chose theside with the unpaired odor. We hypothesized that due to disrupted sleep patterns, dBTBD9mutant flies would be unable to learn the shock-odor association. However, the current studyreports that the recently generated Drosophila model of RLS shows successful olfactorylearning, despite disturbed sleep patterns, with learning performance levels matching or betterthan wild type flies.

  3. The application of root mean square electrocardiography (RMS ECG for the detection of acquired and congenital long QT syndrome.

    Robert L Lux

    Full Text Available BACKGROUND: Precise measurement of the QT interval is often hampered by difficulty determining the end of the low amplitude T wave. Root mean square electrocardiography (RMS ECG provides a novel alternative measure of ventricular repolarization. Experimental data have shown that the interval between the RMS ECG QRS and T wave peaks (RTPK closely reflects the mean ventricular action potential duration while the RMS T wave width (TW tracks the dispersion of repolarization timing. Here, we tested the precision of RMS ECG to assess ventricular repolarization in humans in the setting of drug-induced and congenital Long QT Syndrome (LQTS. METHODS: RMS ECG signals were derived from high-resolution 24 hour Holter monitor recordings from 68 subjects after receiving placebo and moxifloxacin and from standard 12 lead ECGs obtained in 97 subjects with LQTS and 97 age- and sex-matched controls. RTPK, QTRMS and RMS TW intervals were automatically measured using custom software and compared to traditional QT measures using lead II. RESULTS: All measures of repolarization were prolonged during moxifloxacin administration and in LQTS subjects, but the variance of RMS intervals was significantly smaller than traditional lead II measurements. TW was prolonged during moxifloxacin and in subjects with LQT-2, but not LQT-1 or LQT-3. CONCLUSION: These data validate the application of RMS ECG for the detection of drug-induced and congenital LQTS. RMS ECG measurements are more precise than the current standard of care lead II measurements.

  4. Animal models of Central Diabetes Insipidus: Human relevance of acquired beyond hereditary syndromes and the role of oxytocin.

    Bernal, Antonio; Mahía, Javier; Puerto, Amadeo

    2016-07-01

    The aim of this study was to review different animal models of Central Diabetes Insipidus, a neurobiological syndrome characterized by the excretion of copious amounts of diluted urine (polyuria), a consequent water intake (polydipsia), and a rise in the serum sodium concentration (hypernatremia). In rodents, Central Diabetes Insipidus can be caused by genetic disorders (Brattleboro rats) but also by various traumatic/surgical interventions, including neurohypophysectomy, pituitary stalk compression, hypophysectomy, and median eminence lesions. Regardless of its etiology, Central Diabetes Insipidus affects the neuroendocrine system that secretes arginine vasopressin, a neurohormone responsible for antidiuretic functions that acts trough the renal system. However, most Central Diabetes Insipidus models also show disorders in other neurobiological systems, specifically in the secretion of oxytocin, a neurohormone involved in body sodium excretion. Although the hydromineral behaviors shown by the different Central Diabetes Insipidus models have usually been considered as very similar, the present review highlights relevant differences with respect to these behaviors as a function of the individual neurobiological systems affected. Increased understanding of the relationship between the neuroendocrine systems involved and the associated hydromineral behaviors may allow appropriate action to be taken to correct these behavioral neuroendocrine deficits.

    2006-12-01

    Full Text Available Primary immunodeficiency disorders are a heterogeneous group of genetic disorders, with different modes of inheritance, consisting of more than 100 different types. We constructed the DNA banking of primary immunodeficiency disorders for the first time in Iran. The DNA of 31 immunodeficient patients and their families (total of 92 samples were collected, as the first step for construction of DNA banking. DNA was isolated from whole blood by salting out method. Among our patients, Common variable immunodeficiency was the most common disorder, followed by X-linked agammaglobulinemia, Ataxia-telangiectasia, Chronic granulomatous disease, Severe combined immunodeficiency, Hyper IgM syndromes, and Leukocyte adhesion defects. DNA banking is a useful method for further detection of mutation in immunodeficient patients and prenatal diagnosis for presence or absence of the disorder in the fetus which can be confirmed by molecular genetics testing.

    Fungal infections represent a major source of morbidity and mortality in patients with almost all types of immunodeficiencies. These infections may be nosocomial (aspergillosis) or community acquired (cryptococcosis), or both (candidiasis). Endemic mycoses such as histoplasmosis, coccidioidomycosis, and penicilliosis may infect many immunocompromised hosts in some geographic areas and thereby create major public health problems. With the wide availability of oral azoles, antifungal prophylact...

  7. Gastrointestinal opportunistic infections in human immunodeficiency virus disease

    Al Anazi Awadh

    2009-01-01

    Full Text Available Gastrointestinal (GI opportunistic infections (OIs are commonly encountered at various stages of human immunodeficiency virus (HIV disease. In view of the suppressive nature of the virus and the direct contact with the environment, the GI tract is readily accessible and is a common site for clinical expression of HIV. The subject is presented based on information obtained by electronic searches of peer-reviewed articles in medical journals, Cochrane reviews and PubMed sources. The spectrum of GI OIs ranges from oral lesions of Candidiasis, various lesions of viral infections, hepatobiliary lesions, pancreatitis and anorectal lesions. The manifestations of the disease depend on the level of immunosuppression, as determined by the CD4 counts. The advent of highly active antiretroviral therapy has altered the pattern of presentation, resorting mainly to features of antimicrobial-associated colitis and side effects of antiretroviral drugs. The diagnosis of GI OIs in HIV/ acquired immunodeficiency syndrome patients is usually straightforward. However, subtle presentations require that the physicians should have a high index of suspicion when given the setting of HIV infection.

  8. Pneumocystis jirovecii Pneumonia in Human Immunodeficiency Virus Infection.

    Siegel, Marc; Masur, Henry; Kovacs, Joseph

    2016-04-01

    The presentation of Pneumocystis pneumonia (PCP) in previously healthy men having sex with men (MSM) in San Francisco and New York City in 1981 heralded the beginning of the human immunodeficiency virus (HIV) pandemic. Despite a decreasing incidence of PCP among patients with HIV/AIDS (acquired immunodeficiency syndrome) since the advent of combination antiretroviral therapy in the mid-1990s, PCP remains one of the most common AIDS-defining opportunistic infections in the United States and Western Europe. Newer molecular diagnostic tests in conjunction with standard immunofluorescent or colorimetric tests have allowed for more rapid and accurate diagnosis. Although several effective oral and intravenous therapies exist to treat PCP, mortality rates in HIV-infected individuals remain unacceptably high, especially in those with advanced AIDS. The identification of specific mutations in Pneumocystis genes targeted by trimethoprim-sulfamethoxazole has raised concerns about the development of resistance to the drug of choice and may ultimately lead to greater utilization of alternative therapies to treat PCP in the future.

    2015-01-01

    Full Text Available Background: Oral lesions are among the earliest clinical manifestations of human immunodeficiency (HIV infection and are important in early diagnosis and for monitoring the progression to acquired immunodeficiency syndrome (AIDS. The purpose of this study was to determine the prevalence of oral lesions and their relationship with a number of factors in HIV/AIDS patients attending an HIV center.     Methods: A total of 110 HIV-positive patients were examined to investigate the prevalence of oral lesions according to the criteria established by the European Community Clearing House on Oral Problems Related to HIV Infection. An independent T-test was used for correlation of oral lesions with CD4+ count and a χ2 test was used for analysis of the relationship of co-infection with hepatitis B virus (HBV, sexual contact, route of transmission, history of drug abuse, and history of incarceration.   Results: Most of the cases were male patients (82.7%. The mean age across all participants was 36.2±8.1 years. Rampant carries, severe periodontitis and oral candidiasis were the most notable oral lesions. Oral lesions were more prevalent in patients between 26–35 years of age. There was a significant difference between patients with and without pseudomembranous candidiasis and angular cheilitis according to mean level of CD4+.   Conclusion: The most common oral presentations were severe periodontitis, pseudomembranous candidiasis and xerostomia. 

  10. How Many Have Died from Undiagnosed Human Immunodeficiency Virus–Associated Histoplasmosis, A Treatable Disease? Time to Act

    Nacher, Mathieu; Adenis, Antoine; Aznar, Christine; Blanchet, Denis; Vantilcke, Vincent; Demar, Magalie; Carme, Bernard; Couppié, Pierre

    2014-01-01

    Human immunodeficiency virus (HIV)–associated disseminated Histoplasma capsulatum capsulatum infection often mimics tuberculosis. This disease is well know in the United States but is dramatically underdiagnosed in Central and South America. In the Amazon region, given the available incidence data and the regional HIV prevalence, it is expected that, every year, 1,500 cases of histoplasmosis affect HIV patients in that region alone. Given the mortality in undiagnosed patients, at least 600 patients would be expected to die from an undiagnosed but treatable disease. The lack of a simple diagnostic tool and the lack of awareness by clinicians spiral in a vicious cycle and made a major problem invisible for 30 years. The HIV/acquired immunodeficiency syndrome community should tackle this problem now to prevent numerous avoidable deaths from HIV-associated histoplasmosis in the region and elsewhere. PMID:24277783

    Barber, Daniel L.; Andrade, Bruno B; McBerry, Cortez; Sereti, Irini; Sher, Alan

    2013-01-01

    Immune Reconstitution Inflammatory Syndrome (IRIS) is a major adverse event of antiretroviral therapy (ART) in HIV infection, and paradoxically occurs as HIV viremia is suppressed and CD4 T cell numbers recover. IRIS reflects pathogenic immune responses against opportunistic infections acquired during the period of immunodeficiency, but little is understood about the mechanisms of inflammatory pathology. Here we show that IL-6 and CRP levels transiently rise at the time of the IRIS event in H...

    Full Text Available We report the updated classification of primary immunodeficiencies compiled by the Expert Committee of the International Union of Immunological Societies. In comparison to the previous version, more than 30 new gene defects are reported in this updated version. In addition we have added a table of acquired defects that are phenocopies of primary immunodeficiencies. For each disorder, the key clinical and laboratory features are provided. This classification is the most up to date catalogue of all known primary immunodeficiencies and acts as a current reference of the knowledge of these conditions and is an important aid for the molecular diagnosis of patients with these rare diseases.

  1. Mitoxantrone and acquired Long-QT Syndrome. Case presentation. Mitoxantrone y síndrome QT prolongado adquirido. Presentación de un caso.

    Brandy Viera Valdés

    2009-04-01

    Full Text Available The acquired Long-QT Syndrome can be caused by more than 100 non anti-arrhythmic drugs. These drugs block potassium channels; particularly the IKr which extends the ventricular repolarization beyond 450 ms. This syndrome is associated with ventricular helical tachycardia that could potentially cause immediate death. We report a patient with diagnosis of leukaemia who was treated with mitoxantrone and presented syncope. The electrocardiogram showed an interval QTc of 576 ms. After an exclusion diagnosis we concluded that there could be an association with the use of this drug caused by its toxic effects for the cardiac system. Mitoxantrone interferes in ionic transportation through cellular membrane, delays the exit of potassium from the cells and acts in the functioning of ATP asa Na/K altering the ventricular repolarization; however, it is not on the list of drugs that enlarge the QT interval. Our objective with this work is to raise the interest on new reports on this subject, and to establish a more direct causal relation through the evidence derived from new experiences.

    El síndrome QT largo adquirido puede ser producido entre otros aspectos por más de 100 fármacos no antiarrítmicos.

Este síndrome se asocia a taquicardias ventriculares helicoidales con potencial para producir una muerte súbita.

  2. Human immunodeficiency virus-associated disruption of mucosal barriers and its role in HIV transmission and pathogenesis of HIV/AIDS disease.

    Tugizov, Sharof

    2016-01-01

    Oral, intestinal and genital mucosal epithelia have a barrier function to prevent paracellular penetration by viral, bacterial and other pathogens, including human immunodeficiency virus (HIV). HIV can overcome these barriers by disrupting the tight and adherens junctions of mucosal epithelia. HIV-associated disruption of epithelial junctions may also facilitate paracellular penetration and dissemination of other viral pathogens. This review focuses on possible molecular mechanisms of HIV-associated disruption of mucosal epithelial junctions and its role in HIV transmission and pathogenesis of HIV and acquired immune deficiency syndrome (AIDS).

  3. Pneumocystis pneumonia associated with human immunodeficiency virus infection without elevated (1 → 3)-β-D glucan: A case report.

    Kamada, Takahiro; Furuta, Kenjiro; Tomioka, Hiromi

    2016-01-01

    Pneumocystis pneumonia (PCP) caused by Pneumocystis jirovecii is one of the most common opportunistic infections in immunosuppressed patients, particularly in patients with acquired immunodeficiency syndrome (AIDS). (1 → 3)-β-D-glucan is a component of the cell wall of P. jirovecii and other fungi such as Candida sp., Aspergillus sp. and Histoplasma sp. The measurement of serum (1 → 3)-β-D-glucan has been reported to be a highly sensitive test for PCP related to human immunodeficiency virus (HIV-PCP). We report a case of HIV-PCP not associated with elevated serum (1 → 3)-β-D glucan and highlight how HIV-PCP cannot be completely ruled out if (1 → 3)-β-D glucan is negative. PMID:27330956

  4. Epstein-Barr virus immediate-early gene product trans-activates gene expression from the human immunodeficiency virus long terminal repeat

    Acquired immunodeficiency syndrome patients are frequently coinfected with Epstein-Barr virus (EBV). In this report, the authors demonstrate that an EBV immediate-early gene product, BamHI MLF1, stimulates expression of the bacterial chloramphenicol acetyltransferase (CAT) gene linked to the human immunodeficiency virus (HIV) promoter. The HIV promoter sequences necessary for trans-activation by EBV do not include the tat-responsive sequences. In addition, in contrast to the other herpesvirus trans-activators previously studied, the EBV BamHI MLF1 gene product appears to function in part by a posttranscriptional mechanism, since it increases pHIV-CAT protein activity more than it increases HIV-CAT mRNA. This ability of an EBV gene product to activate HIV gene expression may have biologic consequences in persons coinfected with both viruses

  7. Changing patterns of human immunodeficiency virus-associated neuropathology

    Gray Francoise

    2007-01-01

    Full Text Available This paper describes the evolution of the pathogenic concepts associated with the infection by the human immunodeficiency virus (HIV, with emphasis to the pathology of the nervous system. Although the first description of damage to the nervous system in the acquired immunodeficiency syndrome (AIDS only appeared in 1982, the dramatic diffusion of the epidemic worldwide, as well as the invariably rapidly fatal outcome of the disease before the introduction of efficient treatment, generated from the beginning an enormous amount of research and re-thinking on a number of pathogenetic concepts. Less than 25 years after the first autopsy series on AIDS patients were published and the virus responsible for AIDS was identified, satisfactory definition and classification of a number of neuropathological complications of HIV infection have been established. This has led to the establishment of accurate clinical and biological diagnosis of the main neurological complications of the disease, which remain a major cause of disability and death in patients. Clinical and experimental studies have provided essential insight into the pathogenesis of CNS lesions and the natural history of the disorder. The relatively recent introduction of effective antiretroviral therapy in 1995-6 dramatically improved the course of prognosis of HIV disease. However, there remain a number of unsolved pathogenetic issues, the most puzzling of which remains the precise mechanism of neuronal damage underlying the specific HIV-related cognitive disorder (HIV-dementia. In addition, although antiretroviral therapy has changed the course of neurological complications, new issues have emerged, such as the lack of improvement or even paradoxical deterioration of the neurological status in treated patients. Interpretation of these complications remains largely speculative, partly because of the small number of neuropathological studies related to the beneficial consequence of this

  8. Neutralization sensitivity of a simian-human immunodeficiency virus (SHIV-HXBc2P 3.2N) isolated from an infected rhesus macaque with neurological disease

    Simian-human immunodeficiency virus (SHIV) chimerae, after in vivo passage in monkeys, can induce acquired immunodeficiency syndrome (AIDS)-like illness and death. A monkey infected with the molecularly cloned, pathogenic SHIV-HXBc2P 3.2 exhibited multifocal granulomatous pneumonia as well as progressive neurological impairment characterized by tremors and pelvic limb weakness. SHIV-HXBc2P 3.2N was isolated from brain tissue explants and characterized. Viruses with the envelope glycoproteins of SHIV-HXBc2P 3.2N exhibited increased sensitivity to soluble CD4 and several neutralizing antibodies compared with viruses with the parental SHIV-HXBc2P 3.2 envelope glycoproteins. By contrast, viruses with SHIV-HXBc2P 3.2 and SHIV-HXBc2P 3.2N envelope glycoproteins were neutralized equivalently by 2G12 and 2F5 antibodies, which are rarely elicited in HIV-1-infected humans. A constellation of changes involving both gp120 and gp41 envelope glycoproteins was responsible for the difference in susceptibility to neutralization by most antibodies. Surprisingly, the gain of an N-linked glycosylation site in the gp41 ectodomain contributed greatly to neutralization sensitivity. Thus, the environment of the central nervous system, particularly in the context of immunodeficiency, allows the evolution of immunodeficiency viruses with greater susceptibility to neutralization by antibodies

    Over one third of the patients sero-positive for the human immunodeficiency virus (HIV) with signs of the acquired immune deficiency syndrome (AIDS), and under treatment with anti-retroviral therapy (ART), develop the immune reconstitution inflammatory syndrome (IRIS). It is not clear what variables are that determine whether a patient with HIV/AIDS will develop ART-related IRIS, but the best evidence base thus far indicates that HIV/AIDS patients with low CD4 cell count, and HIV/AIDS patient...

  10. Intra-Blood-Brain Barrier Synthesis of Human Immunodeficiency Virus Antigen and Antibody in Humans and Chimpanzees

    Goudsmit, Jaap; Epstein, Leon G.; Paul, Deborah A.; van der Helm, Hayo J.; Dawson, George J.; Asher, David M.; Yanagihara, Richard; Wolff, Axel V.; Gibbs, Clarence J.; Carleton Gajdusek, D.

    1987-06-01

    The presence of human immunodeficiency virus (HIV) antigens in cerebrospinal fluid (CSF) was associated with progressive encephalopathy in adult and pediatric patients with acquired immunodeficiency syndrome (AIDS). HIV antigen was detected in CSF from 6 of 7 AIDS patients with progressive encephalopathy. By contrast, HIV antigen, whether free or complexed, was detected in CSF from only 1 of 18 HIV antibody seropositive patients without progressive encephalopathy and from 0 of 8 experimentally infected chimpanzees without clinical signs. Intra-blood-brain barrier synthesis of HIV-specific antibody was demonstrated in the majority of patients with AIDS (9/12) or at risk for AIDS (8/13) as well as in the experimentally infected chimpanzees, indicating HIV-specific B-cell reactivity in the brain without apparent neurological signs. In 6 of 11 patients with HIV infection, antibodies synthesized in the central nervous system were directed against HIV envelope proteins. Active viral expression appears to be necessary for both the immunodeficiency and progressive encephalopathy associated with HIV infection.

  13. Abdominal CT features and survival in acquired immunodeficiency

    Purpose: HIV-infected patients show a high incidence of abdominal disease. This investigation was made to determine whether abdominal CT provided prognostically relevant information in these patients. Material and Methods: Images from 533 abdominal CT examinations in 339 HIV-infected patients were retrospectively reviewed for signs of abdominal disease, and correlated with clinical data and survival rates. The Kaplan-Meier analysis and rank testing of survival, and proportional hazards regression were used to define prognostic clinical and imaging findings. Results: Of the 339 patients, 278 (82%) showed abnormal abdominal findings on CT. Median survival was 29 months. Of the imaging findings, hepatic masses (n=11), pathologically enlarged lymph nodes (n=48), and ascites (n=7) were associated with poor survival, giving a median survival of respectively 13 months, 15 months, and less than 1 month. These three features showed no association with CD4+-T-lymphocyte count or CDC category. Main determinants of survival were a low CD4+-T-lymphocyte count, and certain abnormal CT findings. Splenomegaly (n=147), hepatomegaly (n=144), and lymphadenopathy (n=111) were the most common abdominal findings on CT but lacked prognostic relevance. Conclusion: Abdominal CT offered prognostic implications in HIV-infected patients and might serve in risk stratification in selected patients. CT features such as hepatic masses, grossly enlarged lymph nodes, or ascites indicate advanced immunosuppression. (orig.)

    Study of the 620 Asian immigrants with tuberculosis notified in the Wandsworth area of south London between 1973 and 1988 showed a bimodal pattern of tuberculosis notifications: in 1977 there was a peak among Asians from East Africa, and in 1981 a peak among those from the Indian subcontinent. There was a mean lag time of five years between clinical presentation and immigration. Logit analysis showed that, although overall more men had tuberculosis than women, glandular tuberculosis was more ...

  17. Human immunodeficiency virus infection presenting as a fatal case of Guillain-Barré syndrome on a background of diabetes mellitus

    Enwere O.O

    2015-06-01

    Full Text Available Background: Guillain-Barré syndrome (GBS, a post-infective acute polyneuropathy, which occurs rarely among Africans, has been associated with HIV infection and less commonly with diabetes mellitus. Aim: The article documents a case of GBS occurring on the setting of HIV infection on a background of diabetes mellitus. Findings: A 47 years old man presented with features of inability to walk, “pins and needles” sensation in the lower limbs, progressive lower limb weakness of 3 days duration and later on admission involving the upper limbs and, finally respiratory distress leading to his death on the 3rd day of hospital admission. He had an antecedent history of a diarrheal illness 3 weeks prior to his admission, and was treated at a private hospital without any complication. He was observed to have concomitant HIV infection and diabetes mellitus. He was not previously known to have any of these diseases and initially diagnosed as having acute diabetic neuropathy. Conclusion: GBS can occur in the setting of HIV infection on a background of DM and may be associated with a poor prognosis. There is a need to have a high index of suspicion in making a diagnosis of GBS in diabetic patients when it occurs concomitantly with HIV infection.

  18. Small Ruminant Lentiviruses (SRLVs Break the Species Barrier to Acquire New Host Range

    Juliano Cezar Minardi da Cruz

    2013-07-01

    Full Text Available Zoonotic events of simian immunodeficiency virus (SIV from non-human primates to humans have generated the acquired immunodeficiency syndrome (AIDS, one of the most devastating infectious disease of the last century with more than 30 million people dead and about 40.3 million people currently infected worldwide. Human immunodeficiency virus (HIV-1 and HIV-2, the two major viruses that cause AIDS in humans are retroviruses of the lentivirus genus. The genus includes arthritis-encephalitis virus (CAEV and Maedi-Visna virus (MVV, and a heterogeneous group of viruses known as small ruminant lentiviruses (SRLVs, affecting goat and sheep. Lentivirus genome integrates into the host DNA, causing persistent infection associated with a remarkable diversity during viral replication. Direct evidence of mixed infections with these two closely related SRLVs was found in both sheep and goats. The evidence of a genetic continuum with caprine and ovine field isolates demonstrates the absence of an efficient species barrier preventing cross-species transmission. In dual-infected animals, persistent infections with both CAEV and MVV have been described, and viral chimeras have been detected. This not only complicates animal trade between countries but favors the risk that highly pathogenic variants may emerge as has already been observed in the past in Iceland and, more recently, in outbreaks with virulent strains in Spain. SRLVs affecting wildlife have already been identified, demonstrating the existence of emergent viruses adapted to new hosts. Viruses adapted to wildlife ruminants may acquire novel biopathological properties which may endanger not only the new host species but also domestic ruminants and humans. SRLVs infecting sheep and goats follow a genomic evolution similar to that observed in HIV or in other lentiviruses.

  19. Morphological changes in the digestive system of 93 human immunodeficiency virus positive patients: an autopsy study

    Lucinda Calheiros Guimarães

    2012-04-01

    Full Text Available Involvement of the digestive system in patients with acquired immunodeficiency syndrome (AIDS is frequent and many changes in these patients are diagnosed only at autopsy. There are few studies of autopsy with detailed analysis of this system and only one was conducted in Brazil. We evaluated each segment of the digestive system in 93 consecutive autopsies of patients infected with human immunodeficiency virus (HIV and the importance of these lesions to death. Of these, 90 (96.8% patients had AIDS. We reviewed medical records, autopsy reports and histological sections from tongue to rectum stained with hematoxylin-eosin. When necessary, we analyzed special stains and immunohistochemistry to investigate infections. There was damage to the digestive system in 73 (78.5% cases. The most common infections were candidiasis (42%, cytomegalovirus (29%, histoplasmosis (11.8%, toxoplasmosis (9.7% and mycobacterial infection (9.7%. Malignancies were rare, present in four (4.3% cases (two Kaposi's sarcoma, one adenocarcinoma and one metastatic embryonal carcinoma. All segments showed lesions: tongue (48.6%, esophagus (44.8%, stomach (44.7%, colon (43.2% and small intestine (28.9%. The lesions found were immediate cause of death in five (5.4% cases. In another 36 (38.7% cases the basic disease was systemic and also compromised the digestive system.

  20. Knowledge, attitude, and beliefs of young, college student blood donors about Human immunodeficiency virus

    2014-01-01

    Full Text Available Introduction: Young people, who tend to be healthy, idealistic, and motivated, are an excellent pool of potential voluntary unpaid blood donors. Recruiting and retaining young blood donors improves the long term safety and sufficiency of a country′s blood supply. Knowledge, attitude, and beliefs about Human immunodeficiency virus (HIV should play an important role in prevention of disease transmission. Materials and Methods: This study was a questionnaire based survey, conducted to explore the levels of knowledge, attitude, and beliefs about HIV in young college student blood donors. Results: The results showed that the proportion of participants with comprehensive knowledge of HIV prevention and transmission was lesser than expected. Increase in education level and male gender was found to be significantly associated with high HIV-related knowledge. The responses on the different aspects of HIV-related attitude were also varied and there is still stigma associated with Acquired Immunodeficiency Syndrome (AIDS even in the educated groups. Discussion: There was a spectrum of myths and misperceptions emphasizing the need of education that recognizes the social context of attitude towards HIV. Results from this study may contribute to the development of appropriate educational and training material for this group of donors which in turn, may assist in achieving the elusive goal of safe blood supply in future.

  1. The relationship between personality traits and AIDS in patients with human immunodeficiency virus.

    2016-06-01

    This study carried out to survey the relationship between personality traits and Acquired Immunodeficiency Syndrome (AIDS) in patients with human immunodeficiency virus. This case-control study was conducted on 79 AIDS patients of Triangle Clinic in Arak (case group) and 80 healthy people of Valiasr Hospital in Arak (control group). Demographic information checklist and Cloninger' Temperament and Character inventory (TCI) were two instruments applied in the study. SPSS software V.19 and tests independent t-tests, Chi squared and Spearman correlation coefficient were used for data analysis with significant level of control group was significantly higher, and there was a significant difference between two groups variables (P-0.000). The novelty seeking had the highest average in the AIDS patients with a history of addiction (M:74.00), and there was statistically significant difference between perseverance variable (P-0.021) and cooperativeness variable (P-0.041) in the two groups of AIDS patients. There was a significant relationship between novelty seeking and age at the onset of AIDS (P-0.038), harm avoidance and age at the onset of addiction (P-0.046), persistence and age at the onset of AIDS (P-0.035) and the time infected with HIV (P-0.033). It is found that two groups are different due to the personalities, so it is essential to consider the personality traits in order to prevent AIDS and also successfully treat patients suffering from AIDS.

  2. 5-azacytidine and 5-azadeoxycytidine inhibit human immunodeficiency virus type 1 replication in vitro.

    Bouchard, J; Walker, M C; Leclerc, J M; Lapointe, N; Beaulieu, R; Thibodeau, L

    1990-01-01

    Chemotherapeutic agents which affect the integration, stability, or inducibility of the human immunodeficiency virus (HIV) provirus would have considerable value in treating acquired immunodeficiency syndrome. Two nucleoside analogs of cytosine, 5-azacytidine and 5-azadeoxycytidine, which seem to have such value because of their capabilities to affect both the stability and the methylation patterns of the nucleic acids into which they are incorporated, were tested for their ability to inhibit the replication of HIV type 1 (HIV-1) in human CEM T cells in vitro. 5-Azadeoxycytidine (1 microM) completely inhibited HIV replication in CEM cells, by the criteria of reduced viral antigen expression and decreased supernatant reverse transcriptase activity, with little toxicity for the treated cells. 5-azacytidine (1 microM) also inhibited HIV replication, but less effectively. When added 2 or more h after CEM cells were infected with HIV-1, both 5-azacytosine derivatives were less effective than they were when added at the time of infection. Even 2 h of exposure to 5-azadeoxycytidine was sufficient for inhibition of HIV replication. Although long exposure to either analog at concentrations of 1 microM would result in pronounced cellular cytotoxicity, the the fact that short exposures to the same dose of drug inhibit HIV replication but are not toxic for the cells implies that cellular toxicity itself is not an important mechanism of the antiviral action of the analogs.

  3. School placement for human immunodeficiency virus-infected children: the Baltimore City experience.

    Santelli, J S; Birn, A E; Linde, J

    1992-05-01

    Over the past 6 years, the city of Baltimore has successfully implemented a school placement policy for human immunodeficiency virus (HIV)-infected children and children with acquired immunodeficiency syndrome (AIDS). Both policy and specific procedures are based on nationally promulgated guidelines. School placement policy is part of an overall AIDS policy that includes education of students and staff and adoption of universal precautions to prevent transmission of communicable diseases in school. Implementation has been marked by excellent collaboration between the departments of health and education. Important policy components include expedited clinical investigation of each case, an interagency review panel, strict protection of confidentiality, a restricted setting for certain children, a school site visit for each placement, and continued monitoring of the school placement by school nurses. Many HIV-infected students need special educational services and/or school health services. The Baltimore City school placement process has avoided the exaggerated publicity endured by some communities, where media reporting has aggravated community fears and invaded the lives of families with HIV-infected children. Baltimore City has succeeded in ensuring access to education, protecting families' confidentiality, and providing special care for HIV-infected students. Local communities should emphasize national guidelines in designing school placement policies for HIV-infected children. School placement policies work best in the context of a comprehensive policy incorporating AIDS education and care. PMID:1579392

    Background Ciguatoxins (CTXs) are polyether marine neurotoxins found in multiple reef-fish species and are potent activators of voltage-gated sodium channels. It is estimated that up to 500,000 people annually experience acute ciguatera poisoning from consuming toxic fish and a small percentage of these victims will develop a chronic, multisymptom, multisystem illness, which can last years, termed a Chronic Inflammatory Response Syndrome (CIRS). Symptoms of ciguatera CIRS include fatigue, cog...

    2012-03-01

    The rapid emergence of AIDS in humans during the period between 1980 and 2000 has led to extensive efforts to understand more fully similar etiologic agents of chronic and progressive acquired immunodeficiency disease in several mammalian species. Lentiviruses that have gene sequence homology with human immunodeficiency virus (HIV) have been found in different species (including sheep, goats, horses, cattle, cats, and several Old World monkey species). Lentiviruses, comprising a genus of the Retroviridae family, cause persistent infection that can lead to varying degrees of morbidity and mortality depending on the virus and the host species involved. Feline immunodeficiency virus (FIV) causes an immune system disease in domestic cats (Felis catus) involving depletion of the CD4+ population of T lymphocytes, increased susceptibility to opportunistic infections, and sometimes death. Viruses related to domestic cat FIV occur also in a variety of nondomestic felids. This is a brief overview of the current state of knowledge of this large and ancient group of viruses (FIVs) in South America. PMID:22590677

  7. Immune reconstitution inflammatory syndrome due to Mycobacterium avium complex successfully followed up using 18 F-fluorodeoxyglucose positron emission tomography-computed tomography in a patient with human immunodeficiency virus infection: A case report

    In human immunodeficiency virus (HIV)-infected patients, immune reconstitution inflammatory syndrome (IRIS) due to nontuberculous mycobacteria (NTM) infection is one of the most difficult types of IRIS to manage. 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) has been suggested as a useful tool for evaluating the inflammatory status of HIV-infected patients. We present the first case of Mycobacterium avium complex (MAC)-associated IRIS (MAC-IRIS) that was successfully followed up using 18 F-FDG PET/CT. A 44-year-old homosexual Japanese man was referred to our hospital with fever and dyspnea. He was diagnosed with Pneumocystis jiroveci pneumonia and found to be HIV positive. After the initiation of combined antiretroviral therapy (cART), the patient’s mediastinal and bilateral hilar lymphadenopathy gradually enlarged, and bilateral infiltrates appeared in the upper lung fields. 18 F-FDG PET/CT was performed five months after the initiation of cART and showed intense accumulation of fluorodeoxyglucose (FDG) corresponding to the lesions of infiltration as well as the mediastinal and bilateral hilar lymphadenopathy. A bronchial wash culture and pathology findings led to a diagnosis of MAC-IRIS. Anti-mycobacterial chemotherapy with rifampicin, ethambutol, clarithromycin, and levofloxacin was started. One year after the chemotherapy was initiated, there was a significant reduction in FDG uptake in the area of the lesions except in the mediastinal lymph node. This implied incomplete resolution of the MAC-IRIS-related inflammation. Anti-mycobacterial chemotherapy was continued because of the residual lesion. To date, the patient has not experienced a recurrence of MAC-IRIS, a period of nine months. We present a case of MAC-IRIS in an HIV-infected patient whose disease activity was successfully followed up using 18 F-FDG PET/CT. Our data suggest that 18 F-FDG PET/CT is useful for evaluating the disease activity of NTM-IRIS and

    2016-03-01

    Syndromic diarrhea/tricho-hepato-enteric syndrome (SD/THE) is a rare, autosomal recessive and severe bowel disorder mainly caused by mutations in the tetratricopeptide repeat domain 37 (TTC37) gene which act as heterotetrameric cofactors to enhance aberrant mRNAs decay. The phenotype and immune profiles of SD/THE overlap those of primary immunodeficiency diseases (PIDs). Neonates with intractable diarrhea underwent immunologic assessments including immunoglobulin levels, lymphocyte subsets, lymphocyte proliferation, superoxide production, and IL-10 signaling function. Candidate genes for PIDs predisposing to inflammatory bowel disease were sequencing in this study. Two neonates, born to nonconsanguineous parents, suffered from intractable diarrhea, recurrent infections, and massive hematemesis from esopharyngeal varices due to liver cirrhosis or accompanying Trichorrhexis nodosa that developed with age and thus guided the diagnosis of SD/THE compatible to TTC37 mutations (homozygous DelK1155H, Fs*2; heterozygous Y1169Ter and InsA1143, Fs*3). Their immunologic evaluation showed normal mitogen-stimulated lymphocyte proliferation, superoxide production, and IL-10 signaling, but low IgG levels, undetectable antibody to hepatitis B surface antigen and decreased antigen-stimulated lymphocyte proliferation. A PubMed search for bi-allelic TTC37 mutations and phenotypes were recorded in 14 Asian and 12 non-Asian cases. They had similar presentations of infantile onset refractory diarrhea, facial dysmorphism, hair anomalies, low IgG, low birth weight, and consanguinity. A higher incidence of heart anomalies (8/14 vs 2/12; P = 0.0344, Chi-square), nonsense mutations (19 in 28 alleles), and hot-spot mutations (W936Ter, 2779-2G>A, and Y1169Ter) were found in the Asian compared with the non-Asian patients. Despite immunoglobulin therapy in 20 of the patients, 4 died from liver cirrhosis and 1 died from sepsis. Patients of all ethnicities with SD/THE with the characteristic

    Full Text Available The medical records of patients with AIDS admitted to a general hospital in Brazil from 1989 to 1997 were reviewed retrospectively with the aim at defining the frequency and etiology of fever of undetermined origin (FUO in HIV-infected patients of a tropical country and to evaluate the usefulness of the main diagnostic procedures. 188 (58.4% out of 322 patients reported fever at admission to hospital and 55 (17.1% had FUO. Those with FUO had a mean CD4+ cell count of 98/ml. A cause of fever was identified for 45 patients (81.8%. Tuberculosis (32.7%, Pneumocystis carinii pneumonia (10.9%, and Mycobacterium avium complex (9.1% were the most frequent diagnoses. Other infectious diseases are also of note, such as cryptococcal meningitis (5.5%, sinusitis (3.6%, Salmonella-S. mansoni association (3.6%, disseminated histoplasmosis (3.6%, neurosyphilis (1.8%, and isosporiasis (1.8%. Four patients had non-Hodgkin's lymphoma (7.3%. We conclude that an initial aggressive diagnostic approach should be always considered because biopsies (lymph node, liver and bone marrow produced the highest yield in the diagnosis of FUO and the majority of the diagnosed diseases are treatable. The association of diseases is common and have contributed to delay the final diagnosis of FUO in most cases. In our study area the routine request of hemocultures for Salmonella infection and the investigation of cryptococcal antigen in the serum should be considered.Revisaram-se os prontuários médicos de pacientes com AIDS e febre de origem indeterminada (FOI com o objetivo de definirem-se as causas de FOI em indivíduos HIV positivos em um país tropical e, ainda, determinar o valor dos procedimentos diagnósticos mais utilizados. Cento e oitenta e oito (58,4% de 322 pacientes apresentavam febre à internação e 55 (17,1% preencheram os critérios de FOI. A contagem média de CD4+ no grupo com FOI era de 98 células/ml. Definiu-se a causa da febre em 45 pacientes (81,8%. As seguintes doenças infecciosas predominaram como causa de FOI: Tuberculose (32,7%, pneumonia pelo Pneumocystis carinii (10,9% e Mycobacterium avium complex (9,1%. Outras doenças infecciosas merecem destaque: meningite criptocócica (5,5%, sinusite (3,6%, associação Salmonella-S. mansoni (3,6%, histoplasmose disseminada (3,6%, neuro-sífilis (1,8% e isosporíase (1,8%. No grupo das neoplasias, quatro pacientes (7,3% apresentaram linfomas não-Hodgkin disseminados. As biópsias de linfonodos, de fígado e de medula óssea responsabilizaram-se pelo maior número de diagnósticos definitivos na presente casuística. A associação de doenças mostrou-se comum e atrasou o diagnóstico da febre na maioria dos casos. Em nossa região, a realização rotineira de hemoculturas visando identificar os indivíduos com salmonelose prolongada associada à esquistossomose e a pesquisa de antígeno circulante para Cryptococcus neoformans devem ser consideradas nos pacientes com AIDS e FOI.

    Full Text Available Bioethical aspects related with the prevention, diagnosis and treatment of patients with AIDS are present in the Cuban strategy to fight the epidemic. Through the revision of the essentials and principles of Bioethics, we analyze the problems that doctors face when treating these patients and aspects related with education for health in the case of this disease. It also outlines the association between these principles and the disposition, manifested or not, of theses patients to be part of some researches. This infection should be the target of permanent analysis by the Bioethics due to the constant challenges that it represent for medical staff and for society, either for the prevention, treatment and care, or for other kids of actions. Cuba has exceptional results in this field.Aspectos éticos relacionados con la prevención, diagnóstico y tratamiento a los pacientes con SIDA, están presentes en la estrategia cubana para el enfrentamiento de la epidemia. A través de una revisión de los estatutos o principios de la Bioética, se analizan los problemas que enfrenta el médico al tratar a estos pacientes y los aspectos relacionados con la educación para la salud en el caso de la enfermedad; también se destaca la relación con estos principios y el deseo expreso o no de los pacientes de someterse a determinadas investigaciones. El VIH/sida tiene que constituir una situación de análisis permanente de la Bioética por los desafíos constantes del personal de salud y la sociedad, tanto para la prevención, cuidado y tratamiento como para otras acciones. Cuba exhibe resultados excepcionales, diferentes al resto del mundo.

    Conclusion: The use of CPT for people living with HIV/AIDS was found to be good in JUSH with regard to initiation and dosage. However, the practice of discontinuation of CTX, documentation of ADRs and follow-up for adverse effects of CTX should be improved by proper implementation and adhering to the national guideline of CPT.

  17. Assessment of sexual risk behaviors and perception of vulnerability to sexually transmitted diseases/acquired immunodeficiency syndrome in women, 1999–2012: a population based survey in a medium-sized Brazilian city

    Marilia Arndt Mesenburg

    2014-08-01

    Full Text Available Sexual behavior is a key factor for susceptibility to sexually transmitted diseases. An evaluation of the sexual behavior of women at reproductive age was conducted in 1999. A replication of this study aims to evaluate the current situation and identify changes in sexual behavior, 13 years later. This is a population-based cross-sectional study, conducted with 1071 women in Pelotas, Brazil. Compared to the 1999 study, a 14% increase in early sexual debut and an 8% decrease in the non-use of condoms were observed in 2012. The proportion of women who reported anal sex doubled between these periods. There was no trend of increase or decrease in the prevalence of behaviors with distinct patterns being observed for each of them. Reduction of non-use of condoms may be an indicator of the effectiveness of campaigns to promote safe sex. However, the increased prevalence of early sexual debut and anal sex indicates the need for campaigns to continue and to expand their focus, especially among vulnerable groups.

  18. Late Onset Combined Immunodeficiency Presenting with Recurrent Pneumocystis jiroveci Pneumonia

    Ilias Papakonstantinou

    2014-01-01

    Full Text Available Late onset combined immunodeficiency (LOCID is a recently described variant of common variable immunodeficiency (CVID, involving adult patients presenting with opportunistic infections and/or low CD4+ lymphocyte counts. A 36-year-old male with unremarkable past medical history presented with fever, respiratory failure, and lymphocytopenia. He was found to have Pneumocystis jiroveci pneumonia (PJP, subsequently complicated by recurrent hospital-acquired Pseudomonas aeruginosa pneumonia and immune reconstitution phenomena, attributed to restoration of immunoglobulin levels. Clinicians should be aware of LOCID, which could be confused with HIV infection/AIDS or idiopathic CD4 lymphocytopenia. In the English bibliography there is only one case report, where PJP was the initial presentation of CVID (that case would probably be classified as LOCID. Phenomena of immune reconstitution are described in various settings, including primary immunodeficiency, manifesting as temporary clinical and radiologic deterioration and leading to misperceptions of therapeutic failure and/or presence of alternative/additional diagnoses.

    2007-08-01

    Full Text Available Abstract Background The human immunodeficiency virus type 1(HIV-1 is a complex retrovirus and the causative agent of acquired immunodeficiency syndrome (AIDS. The HIV-1 Vpu protein is an oligomeric integral membrane protein essential for particle release, viral load and CD4 degradation. In silico models show Vpu to form pentamers with an ion channel activity. Results Using Vpu proteins from a primary subtype C and the pNL4-3 subtype B isolates of HIV-1, we show oligomerization of the full-length protein as well as its transmembrane (TM domain by genetic, biochemical and biophysical methods. We also provide direct evidence of the presence of Vpu pentamers in a stable equilibrium with its monomers in vitro. This was also true for the TM domain of Vpu. Confocal microscopy localized Vpu to the endoplasmic reticulum and Golgi regions of the cell, as well as to post-Golgi vesicles. In fluorescence resonance energy transfer (FRET experiments in live cells we show that Vpu oligomerizes in what appears to be either the Golgi region or intracellular vesicles, but not in the ER. Conclusion We provide here direct evidence that the TM domain, is critical for Vpu oligomerization and the most favourable channel assembly is a pentamer. The Vpu oligomerization appears to be either the Golgi region or intracellular vesicles, but not in the ER.

  20. Fusion as a mediator of cytolysis in mixtures of uninfected CD4+ lymphocytes and cells infected by human immunodeficiency virus

    The authors describe an unusual type of cytopathology in which uninfected CD4+ (helper/inducer) cells (cells expressing the human leukocyte antigen CD4) interact with cells persistently infected with the human immunodeficiency virus (HIV). Prior antigenic stimulation was not required, since CD4+ cells taken either from healthy persons without anti-HIV antibodies or from individuals with anti-HIV antibodies were capable in inducing cytolysis. Neither CD8+ (suppressor/cytotoxic) nor CD16+ (natural killer) cells mediated the reaction. Light microscopic and autoradiographic studies revealed that, prior to cytolysis, multinucleated giant cells were formed from fusions between HIV-infected cells and large numbers of uninfected CD4+ lymphocytes. These data may explain the paradox that exists in vivo in which a dramatic depletion of CD4+ lymphocytes occurs in the presence of a small number of HIV-infected CD4+ cells. These new insights into the pathogenesis of acquired immunodeficiency syndrome (AIDS) may lead to future therapeutic strategies

  1. Acquired causes of intestinal malabsorption.

    van der Heide, F

    2016-04-01

    This review focuses on the acquired causes, diagnosis, and treatment of intestinal malabsorption. Intestinal absorption is a complex process that depends on many variables, including the digestion of nutrients within the intestinal lumen, the absorptive surface of the small intestine, the membrane transport systems, and the epithelial absorptive enzymes. Acquired causes of malabsorption are classified by focussing on the three phases of digestion and absorption: 1) luminal/digestive phase, 2) mucosal/absorptive phase, and 3) transport phase. Most acquired diseases affect the luminal/digestive phase. These include short bowel syndrome, extensive small bowel inflammation, motility disorders, and deficiencies of digestive enzymes or bile salts. Diagnosis depends on symptoms, physical examination, and blood and stool tests. There is no gold standard for the diagnosis of malabsorption. Further testing should be based on the specific clinical context and the suspected underlying disease. Therapy is directed at nutritional support by enteral or parenteral feeding and screening for and supplementation of deficiencies in vitamins and minerals. Early enteral feeding is important for intestinal adaptation in short bowel syndrome. Medicinal treatment options for diarrhoea in malabsorption include loperamide, codeine, cholestyramine, or antibiotics. PMID:27086886

    2008-01-01

    The disease course of human immunodeficiency virus (HIV) is often altered by existing or newly acquired coinfections. Treatment or prevention of these concomitant infections often improves the quality and duration of life of HIV-infected persons. The impact of helminth infections on infections with HIV is less clear. However, HIV is frequently most problematic in areas where helminth infections are common. In advance of the widespread distribution of drugs for elimination of lymphatic filaria...

    Full Text Available BACKGROUND: Human Immunodeficiency Virus (HIV /Acquired Immunodeficiency Syndrome (AIDS is increasing at an alarming rate globally. It has now become a major challenge & threat to public health. HIV infection in women occur primarily during their reproductive years, hence pregnancy provides a unique opportunity for implementing prevention strategies against HIV infection. If we estimate seroprevalence in pregnancy, the effective & timely intervention will reduce the transmission of infection to newborns. AIMS: To study the seroprevalence of HIV infection in pregnancy in a tertiary care hospital. SETTING: Antenatal Care Clinic of a Tertiary Care Hospital. DESIGN: A cross-sectional study. MATERIAL AND METHODS: Blood samples of all the pregnant women with written consent were collected and tested for HIV antibodies as per National AIDS Control Organization (NACO guidelines over a period from September 2002 to August 2004. However only those who were HIV seroreactive were included in this study. Spouses of seroreactive pregnant women were also counselled and tested. Statistical analysis was done using Chi-square test. RESULTS: Out of the total 10683 blood samples from pregnant women tested, 147 (1.38% were found to be HIV seroreactive. Seroreactive cases when compiled year-wise, showed increase in the seroprevalence from 1.24% in September 2002 - August 2003 to 1.45% in September 2003 - August 2004. Majority 69 (46.94% seroreactive pregnant women were in the age group of 19-24 years followed by 25-29 years age group (31.29%. Out of 88 spouses of HIV seroreactive pregnant women, 85 (96.59% were found to be HIV seroreactive. CONCLUSION: In the present study, seroprevalence of HIV infection was found to be1.38% amongst pregnant women.

  5. A novel thymoma-associated immunodeficiency with increased naive T cells and reduced CD247 expression.

    The mechanisms underlying thymoma-associated immunodeficiency are largely unknown, and the significance of increased blood γδ Τ cells often remains elusive. In this study we address these questions based on an index patient with thymoma, chronic visceral leishmaniasis, myasthenia gravis, and a marked increase of rare γδ T cell subsets in the peripheral blood. This patient showed cutaneous anergy, even though he had normal numbers of peripheral blood total lymphocytes as well as CD4(+) and CD8(+) T cells. Despite his chronic infection, analyses of immunophenotypes and spectratyping of his lymphocytes revealed an unusual accumulation of naive γδ and αβ T cells, suggesting a generalized T cell activation defect. Functional studies in vitro demonstrated substantially diminished IL-2 and IFN-γ production following TCR stimulation of his "untouched" naive CD4(+) T cells. Biochemical analysis revealed that his γδ and αβ T cells carried an altered TCR complex with reduced amounts of the ζ-chain (CD247). No mutations were found in the CD247 gene that encodes the homodimeric ζ protein. The diminished presence of CD247 and increased numbers of γδ T cells were also observed in thymocyte populations obtained from three other thymoma patients. Thus, our findings describe a novel type of a clinically relevant acquired T cell immunodeficiency in thymoma patients that is distinct from Good's syndrome. Its characteristics are an accumulation of CD247-deficient, hyporresponsive naive γδ and αβ T cells and an increased susceptibility to infections. PMID:25732729

    Carcinoma of the breast is the most common malignancy in women in the United States. More than 40% of patients with human immunodeficiency virus (HIV) infection develop cancer during their illness, but breast cancer has seldom been reported. Twenty patients with breast cancer and HIV infection seen at the University of Miami/Jackson Memorial Hospital between January 1988 and August 2000 were retrospectively analyzed. Seventeen patients had a previous or concurrent diagnosis of HIV at the time of the breast cancer diagnosis. Their CD4 count ranged from 13-1126/microL (median, 309/microL). Most patients were premenopausal (16 of 20), with ages ranging from 31-61 years (median, 44 years). All stages of breast cancer were seen: ductal carcinoma in situ (2 patients), stage I (1 patient), stage II (9 patients), stage III (6 patients), and stage IV (2 patients). Ten tumors had estrogen receptors. Four of the 13 patients who underwent axillary lymph node dissection had abnormal lymph node findings, including 2 with follicular hyperplasia and 2 with caseating granulomas. Seven patients received chemotherapy with very poor tolerance. Estrogen receptor-positive patients were treated with tamoxifen. Of the 18 patients who presented with local disease, 7 have died: 2 of breast cancer, 4 of acquired immunodeficiency syndrome, and 1 of cardiac arrest. Nine patients remain free of disease (5 of them > 5 years) and 2 patients are alive with metastatic disease. Breast cancer in the HIV-positive population is similar to that seen in seronegative women. Most of the patients that are long-term survivors were treated with surgery and tamoxifen. The benefits of adjuvant chemotherapy are not clear. PMID:11899415

    Objective To investigate the risk factors attributable to tuberculosis-related deaths in areas with human immunodeficiency virus (HIV) infection epidemics. Methods A prospective cohort study of newly registered patients in tuberculosis (TB) dispensaries in six representative Chinese provinces was conducted from September 1, 2009 to August 31, 2011. Risk factors for TB-associated death were identified through logistic regression analysis. Results Of 19,103 newly registered pulmonary TB patients, 925 (4.8%) were found to be HIV-positive. Miliary TB and acid-fast bacillus smear-negative TB were more common among these patients. Out of a total of 322 (1.7%) deaths that occurred during TB treatment, 85 (26%) of the patients were co-infected with HIV. Multivariate analysis revealed that HIV infection was the strongest predictor of death [adjusted odds ratio (aOR) 7.86]. Other significant mortality risk factors included presentation with miliary TB (aOR 4.10; 95% confidence interval: 2.14-7.88), ≥35 years of age (aOR 3.04), non-Han ethnicity (aOR 1.67), and farming as an occupation (aOR 1.59). For patients with TB/HIV co-infection, miliary TB was the strongest risk factor for death (aOR 5.48). A low CD4 count (≤200 cells/µL) (aOR 3.27) at the time of TB treatment initiation and a lack of antiretroviral therapy (ART) administration (aOR 3.78) were also correlated with an increased risk of death. Conclusion Infection with HIV was independently associated with increased mortality during TB treatment. Offering HIV testing at the time of diagnosis with TB, early TB diagnosis among HIV/acquired immunodeficiency syndrome patients, and the timely provision of ART were identified as the key approaches that could reduce the number of HIV-associated TB deaths.

  9. Radiographic findings in immunodeficiency

    This paper reviews the chest radiographs and high-resolution CT (HRCT) scans in patients with immunodeficiency disorders and define the role of HRCT. Thirty-three cases were retrospectively graded according to the consensus of two radiologists. Patients with HIV seropositivity and asthma were excluded. HRCT was performed in 12 cases with standard techniques. Diagnoses included common variable hypogammaglobulinemia (n = 19), X-linked agammaglobulinemia (n = 4), chronic mucocutaneous candidiasis (n = 4), and selective immunoglobulin g deficiencies (n = 2). Chest radiographs showed bronchiectasis in 11 of 33 cases with a predominant lower lobe distribution (82%). Nodules were present in six cases and mucus plugs in four cases. HRCT showed bronchiectasis in nine of 12 cases; in five of these nine cases, bronchiectasis was not apparent on chest radiographs. Other HRCT findings included segmental air trapping (four of 12), mucus plugs (three of 12), hazy consolidation (four of 12), nodules (five of 12), and bronchiolectasis (two of 12). Therapy was altered in seven of 12 cases in which HRCT was performed. Most pertinent to clinical management were the presence of a thymoma (n = 1) and severe focal of diffuse bronchiectasis

    Pneumocystis jirovecii colonization has been associated with non-acquired immune deficiency syndrome (AIDS) pulmonary comorbidity. We used spirometry to measure pulmonary function and analyzed oral wash specimens by quantitative polymerase chain reaction (PCR), targeting the large mitochondrial ribosomal subunit. For sensitivity control, a blinded subsample was subjected to touch-down PCRs, targeting both large and small ribosomal subunits and the major surface glycoprotein. Pneumocystis jirovecii deoxyribonucleic acid (DNA) was detected in 1 of 156 (95% confidence interval, .1%-3.5%) virologically suppressed human immunodeficiency virus (HIV)-infected individuals confirmed by all PCR methods. Thus, prevalence of P jirovecii colonization was low and unlikely to be a major cause of pulmonary comorbidity in this group of well treated HIV-infected individuals. PMID:27006967

    2016-01-01

    Full Text Available HIV/AIDS patients often present with orogenital ulcers. In the immunocompromised patient diagnosis of these ulcers pose a challenge, as there is a myriad of etiologies. We present a case of an HIV/AIDS patient with recurrent orogenital aphthosis that was confirmed to have concomitant diagnosis of Behcet's disease. Proper awareness of the causes of these ulcers is essential for prompt and effective treatment. While rare causes may be at the bottom of a differential list in an immunocompetent host, when HIV/AIDS is involved these rare causes often percolate to the top.

  14. Inflammatory bowel disease: is it a primary immunodeficiency?

    Glocker, Erik; Grimbacher, Bodo

    2012-01-01

    Inflammatory bowel diseases (IBD) such as ulcerative colitis and Crohn's disease are chronic and relapsing conditions, characterized by abdominal pain, diarrhea, bleeding and malabsorption. IBD has been considered a hyperinflammatory state due to disturbed interactions between the immune system and the commensal bacterial flora of the gut. However, there is evidence that Crohn's disease might be the consequence of a reduced release of pro-inflammatory cytokines and an impaired acute inflammatory response, thereby suggesting that IBD might be an immunodeficiency rather than an excessive inflammatory reaction. This theory has been supported by observations in patients with primary immunodeficiencies such as the Wiskott-Aldrich syndrome and IPEX (immunodysregulation, polyendocrinopathy, enteropathy, X-linked syndrome). In contrary, defects in the anti-inflammatory down-regulation of the immune response as they are seen in patients with Mendelian defects in the IL10 signaling pathway support the hyper-inflammatory theory. In this review, we describe and discuss primary immunodeficiencies associated with IBD and show that the bowel is a highly sensitive indicator of dysregulations, making IBD a model disease to study and identify key regulators required to balance the human mucosal immune system.

  16. Primary Immunodeficiencies with Elevated IgE.

    Mogensen, Trine H

    2016-01-01

    In recent years a number of primary immunodeficiencies (PIDs) characterized by elevated Immunoglobulin E (IgE) levels have been uncovered and termed as Hyper-IgE syndrome (HIES). In addition to the elevated levels of IgE, patients with these PIDs display a spectrum of infections by staphylococci and fungi, and in some cases viruses, particularly affecting skin and lungs. Most of these PIDs also have a non-infectious phenotype, comprising musculoskeletal, vascular, and neurological abnormalities. The genetic basis for the majority of conditions with elevated IgE has now been established and includes mutations in STAT3, DOCK8, TYK2, and most recently PGM3 molecules. However, in some patients with the relevant phenotype, mutations in these molecules are not identified, suggesting additional genetic etiologies of HIES not yet discovered. As the immunological and molecular basis of HIES is being unraveled, important insights are emerging that may have implications for our understanding of basic principles of immunology and protective immunity as well as for the pathogenesis and clinical management of patients with these complex and challenging PIDs. In this review, are presented the current knowledge on the clinical presentation, infectious phenotype, and the genetic and immunological pathogenesis of hyper-IgE syndromes as well as some other PIDs with elevated levels of IgE.

  17. Molecular and biological aspects of the bovine immunodeficiency virus.

    Corredor, Andrea G; St-Louis, Marie-Claude; Archambault, Denis

    2010-01-01

    The bovine immunodeficiency virus (BIV) was isolated in 1969 from a cow, R-29, with a wasting syndrome suggesting bovine leucosis. The virus, first designated bovine visna-like virus, remained unstudied until HIV was discovered in 1983. Then, it was demonstrated in 1987 that the bovine R-29 isolate was a lentivirus with striking similarity to the human immunodeficiency virus (HIV). Moreover, BIV has the most complex genomic structure among all identified lentiviruses shown by several regulatory/accessory genes encoding proteins, some of which are involved in the regulation of virus gene expression. This manuscript aims to review biological and molecular aspects of BIV, with emphasis on regulatory/accessory viral genes/proteins which are involved in virus expression. PMID:20210777

  18. Molecular and genetic basis of X-linked immunodeficiency disorders

    Puck, J.M. (National Center for Human Genome Research, Bethesda, MD (United States))

    1994-03-01

    Within a short time interval the specific gene defects causing three X-linked human immunodeficiencies, agammaglobulinemia (XLA), hyper-IgM syndrome (HIGM), and severe combined immunodeficiency (XSCID), have been identified. These represent the first human disease phenotypes associated with each of three gene families already recognized to be important in lymphocyte development and signaling: XLA is caused by mutations of a B cell-specific intracellular tyrosine kinase; HIGM, by mutations in the TNF-related CD40 ligand, through which T cells deliver helper signals by direct contact with B cell CD40; and XSCID, by mutations in the [gamma] chain of the lymphocyte receptor for IL-2. Each patient mutation analyzed to date has been unique, representing both a challenge for genetic diagnosis and management and an important resource for dissecting molecular domains and understanding the physiologic function of the gene products.

    Full Text Available At present, we are observing eighty-three adult patients with various primary immunodeficiencies (PID of different origin. The aim of our study was to identify the optimal ways for early detection of such disorders. In this work, we present an analysis of initial clinical manifestations of PID in adults. It was revealed that the type of clinical manifestations is quite unique for individual cases. And the patients exhibit quite diverse clinical findings and course of the disorder, even within a single nosological entity. However, infectious syndrome prevailed among others manifestations. Combinations of complex clinical syndromes were not typical to initial PID pattern. We observed polytopic lesions within each single immunopathological syndrome.

    2013-01-01

    Background: Mucocutaneous diseases are among the first-recognized clinical manifestations of acquired immune deficiency syndrome. They function as visual markers in assessing the progression of human immunodeficiency virus (HIV) infection. Given the relative ease of examination of skin, its evaluation remains an important tool in the diagnosis of HIV infection. Objective: To determine the pattern of mucocutaneous manifestations in HIV-positive patients and to correlate their presence with CD4 counts. Materials and Methods: This cross-sectional study included 352 HIV-infected patients seen at PGIMER, Chandigarh, India, over a period of 1 year. The patients were screened for mucocutaneous disorders by an experienced dermatologist. The patients were classified into different stages according to the World Health Organization clinical and immunological staging system. Results: The most prevalent infection was candidiasis, seen in 57 patients (16.2%). Prevalence of candidiasis, dermatophytosis, herpes simplex, herpes zoster, molluscum contagiosum (MC), seborrheic dermatitis, adverse drug reaction, nail pigmentation, xerosis and diffuse hair loss differed statistically according to the clinical stages of HIV infection. There was a statistically significant association between immunological stages of HIV infection and dermatophytosis. Conclusion: Results of our study suggest that mucocutaneous findings occur throughout the course of HIV infection. Dermatoses like MC and dermatophytosis show an inverse relation with CD4 cell count, and these dermatoses can be used as a proxy indicator of advanced immunosuppression to start highly active anti-retroviral therapy in the absence of facilities to carry out CD4 cell count.

  2. Pin1 liberates the human immunodeficiency virus type-1 (HIV-1): Must we stop it?

    Hou, Hai; Wang, Jing-Zhang; Liu, Bao-Guo; Zhang, Ting

    2015-07-01

    Acquired immune deficiency syndrome (AIDS) is mainly caused by the human immunodeficiency virus type-1 (HIV-1). To our knowledge, this is the first review focusing on the vital role of Pin1 in the infection of HIV-1 and the development of AIDS. We and others have demonstrated that Pin1, the only known cis-to-trans isomerase recognizing the pThr/pSer-Pro motifs in proteins, plays striking roles in several human diseases. Interestingly, recent evidence gradually indicates that Pin1 regulates several key steps of the life cycle of HIV-1, including the uncoating of the HIV-1 core, the reverse transcription of the RNA genome of HIV-1, and the integration of the HIV-1 cDNA into human chromosomes. Whereas inhibiting Pin1 suppresses all of these key steps and attenuates the replication of HIV-1, at the same time different PIN1 gene variants are correlated with the susceptibility to HIV-1 infection. Furthermore, Pin1 potentially promotes HIV-1 infection by activating multiple oncogenes and inactivating multiple tumor suppressors, extending the life span of HIV-infected cells. These descriptions suggest Pin1 as a promising therapeutic target for the prevention of HIV-1 and highlight the possibility of blocking the development of AIDS by Pin1 inhibitors. PMID:25913034

  3. Feline immunodeficiency virus infection.

    1989-05-01

    Feline immunodeficiency virus (FIV) (formerly feline T-lymphotropic lentivirus or FTLV) was first isolated from a group of cats in Petaluma, California in 1986. The virus is a typical lentivirus in gross and structural morphology. It replicates preferentially but not exclusively in feline T-lymphoblastoid cells, where it causes a characteristic cytopathic effect. The major structural proteins are 10, 17 (small gag), 28 (major core), 31 (endonuclease?), 41 (transmembrane?), 52 (core precursor polyprotein), 54/62 (reverse transcriptase?), and 110/130 (major envelope) kilodaltons in size. The various proteins are antigenically distinguishable from those of other lentiviruses, although serum from EIAV-infected horses will cross-react with some FIV antigens. Kittens experimentally infected with FIV manifest a transient (several days to 2 weeks) fever and neutropenia beginning 4 to 8 weeks after inoculation. This is associated with a generalized lymphadenopathy that persists for up to 9 months. Most cats recover from this initial phase of the disease and become lifelong carriers of the virus. Complete recovery does not occur to any extent in nature or in the laboratory setting. One experimentally infected cat died from a myeloproliferative disorder several months after infection. The terminal AIDS-like phase of the illness has been seen mainly in naturally infected cats. It appears a year or more following the initial infection in an unknown proportion of infected animals. FIV has been identified in cats from all parts of the world. It is most prevalent in high density populations of free roaming cats (feral and pet), and is very uncommon in closed purebred catteries. Male cats are twice as likely to become infected as females. Older male cats adopted as feral or stray animals are at the highest risk of infection, therefore. The infection rate among freely roaming cats rises throughout life, and reaches levels ranging from less than 1% to 12% or more depending on the

    Two children are presented with autosomal recessive hyper IgE syndrome caused by a mutation in the dedicator of cytokinesis 8 gene (DOCK8). The manifestations are typically severe atopic dermatitis, food allergies, elevated serum IgE concentration, viral skin infections and risk of malignancies. DOCK8 deficiency was first reported in 2009, following the death of the oldest sibling. The youngest sibling was cured after allogenic stem cell transplantation. This case report illustrates the need of awareness of primary immunodeficiency in children with atypical manifestation of atopic dermatitis in combination with recurrent infections. PMID:26692033

    Metin Kanıtez

    2014-01-01

    Full Text Available Highly active antiretroviral therapy (HAART has markedly decreased human immunodeficiency virus- (HIV- related mortality and the incidence of opportunistic infections. The dramatic reduction in HIV-1 RNA and increase in CD4 lymphocyte count mean a recovery in immune function. This restoration in immune function may be associated with paradoxical deterioration in subclinical opportunistic infections in some patients, a condition called immune reconstitution inflammatory syndrome (IRIS. IRIS, a “paradoxical” inflammatory response to either previously treated or subclinical infections or noninfectious diseases, can manifest during the restoration phase of immunity hemophagocytic syndrome (HS which is a very rare complication in patients with acquired immune deficiency syndrome (AIDS. We describe a case of hemophagocytic syndrome associated with IRIS in a patient with AIDS related Burkitt’s leukemia/lymphoma (BL. IRIS was probably the cause of hemophagocytosis for our patient. Zoster infection may facilitate to IRIS. With the increasing number of people with HIV infection and the accompanying use of HAART, much more clinical manifestations of IRIS will be experienced especially in patients given high dose chemotherapy, just like in our case.

    2008-12-01

    Full Text Available Abstract Introduction Acute Human Immunodeficiency Virus infection is associated with a range of neurological conditions. Guillain-Barré syndrome is a rare presentation; acute inflammatory demyelinating polyneuropathy is the commonest form of Guillain-Barré syndrome. Acute inflammatory demyelinating polyneuropathy has occasionally been reported in acute Immunodeficiency Virus infection but little data exists on frequency, management and outcome. Case presentation We describe an episode of Guillain-Barré syndrome presenting as acute inflammatory demyelinating polyneuropathy in a 30-year-old man testing positive for Immunodeficiency Virus, probably during acute seroconversion. Clinical suspicion was confirmed by cerebrospinal fluid analysis and nerve conduction studies. Rapid clinical deterioration prompted intravenous immunoglobulin therapy and early commencement of highly active anti-retroviral therapy. All symptoms resolved within nine weeks. Conclusion Unusual neurological presentations in previously fit patients are an appropriate indication for Immunodeficiency-Virus testing. Highly active anti-retroviral therapy with adequate penetration of the central nervous system should be considered as an early intervention, alongside conventional therapies such as intravenous immunoglobulin.

  15. Respiratory Syncytial Virus Infections in Infants Affected by Primary Immunodeficiency

    Marcello Lanari

    2014-01-01

    Full Text Available Primary immunodeficiencies are rare inherited disorders that may lead to frequent and often severe acute respiratory infections. Respiratory syncytial virus (RSV is one of the most frequent pathogens during early infancy and the infection is more severe in immunocompromised infants than in healthy infants, as a result of impaired T- and B-cell immune response unable to efficaciously neutralize viral replication, with subsequent increased viral shedding and potentially lethal lower respiratory tract infection. Several authors have reported a severe clinical course after RSV infections in infants and children with primary and acquired immunodeficiencies. Environmental prophylaxis is essential in order to reduce the infection during the epidemic season in hospitalized immunocompromised infants. Prophylaxis with palivizumab, a humanized monoclonal antibody against the RSV F protein, is currently recommended in high-risk infants born prematurely, with chronic lung disease or congenital heart disease. Currently however the prophylaxis is not routinely recommended in infants with primary immunodeficiency, although some authors propose the extension of prophylaxis to this high risk population.

  16. Effect of left ventricular dysfunction and viral load on risk of sudden cardiac death in patients with human immunodeficiency virus.

    Moyers, Brian S; Secemsky, Eric A; Vittinghoff, Eric; Wong, Joseph K; Havlir, Diane V; Hsue, Priscilla Y; Tseng, Zian H

    2014-04-01

    Human immunodeficiency virus (HIV)-infected patients are disproportionately affected by cardiovascular disease and sudden cardiac death (SCD). Whether left ventricular (LV) dysfunction predicts SCD in those with HIV is unknown. We sought to determine the impact of LV dysfunction on SCD in patients with HIV. We previously characterized all SCDs and acquired immunodeficiency syndrome (AIDS) deaths in 2,860 consecutive patients in a public HIV clinic from 2000 to 2009. Transthoracic echocardiograms (TTEs) performed during the study period were identified. The effect of ejection fraction (EF), diastolic dysfunction, pulmonary artery pressure, and LV mass on SCD and AIDS death were evaluated: 423 patients had at least 1 TTE; 13 SCDs and 55 AIDS deaths had at least 1 TTE. In the propensity-adjusted analysis, EF 30% to 39% and EF<30% predicted SCD (hazard ratio [HR] 9.5, 95% confidence interval [CI] 1.7 to 53.3, p=0.01 and HR 38.5, 95% CI 7.6 to 195.0, p<0.001, respectively) but not AIDS death. Diastolic dysfunction also predicted SCD (HR 14.8, 95% CI 4.0 to 55.4, p<0.001) but not AIDS death, even after adjusting for EF. The association between EF<40% and SCD was greater in subjects with detectable versus undetectable HIV RNA (adjusted HR 11.7, 95% CI 2.9 to 47.2, p=0.001 vs HR 2.7, 95% CI 0.3 to 27.6, p=0.41; p=0.07 for interaction). In conclusion, LV systolic dysfunction and diastolic dysfunction predict SCD but not AIDS death in a large HIV cohort, with greater effect in those with detectable HIV RNA. Further investigation is needed to thoroughly evaluate the effect of low EF and HIV factors on SCD incidence and the potential benefit of implantable cardioverter-defibrillator therapy in this high-risk population.

  17. Heat Shock Protein–Based Therapeutic Strategies Against Human Immunodeficiency Virus Type Infection

    M. A. Wainberg

    1999-01-01

    Full Text Available Heat shock proteins (hsps and cyclophilins (CypA are intracellular chaperone molecules that facilitate protein folding and assembly. These proteins are selectively expressed in cells following exposure to a range of stress stimuli, including viral infection. Hsp species are highly immunogenic, eliciting humoral, cytotoxic T lymphocyte (CTL, and natural killer (NK cell responses against viruses, tumours, and infectious diseases. This review discusses the roles of stress proteins in immunity and viral life cycles, vis-à-vis the development of Hsp-based therapeutic strategies against human immunodeficiency virus type-1 (HIV-1 infection. Cumulative findings are cited implicating the requirement of CypA in HIV-1 replication and formation of infectious virions. Studies by our group show the upregulated expression of hsp27 and hsp70 during single-cycle HIV infections. These species redistribute to the cell surface following HIV-infection and heat stress, serving as targets for NK and antibody-dependent cellular cytotoxicity. Co-immunoprecipitation and Western blot studies show that hsp27, hsp70, and hsp78 complex with HIV-1 viral proteins intracellularly. Hsp70, hsp56, and CypA are assembled into HIV-1 virions. The ability of hsps to interact with HIV-1 viral proteins, combined with their inherent adjuvant and immunogenic properties, indicates that hsps may serve as vehicles for antigen delivery and the design of vaccines against acquired immunodeficiency syndrome.

  18. Gene therapy for primary immunodeficiencies.

    Fischer, A; Hacein-Bey Abina, S; Touzot, F; Cavazzana, M

    2015-12-01

    Gene therapy has effectively entered Medicine via the field of primary immunodeficiencies (PID). Because hematopoietic stem cells are accessible and because it was understood that genetic correction of lymphocyte progenitor cells carrying a genetic defect impairing differentiation, could result in the production of long-lived T lymphocytes, it was reasoned that ex vivo gene transfer in hematopoietic cells could lead to disease phenotype correction. Retroviral vectors were designed to ex vivo transduce such cells. This has indeed been shown to lead to sustained correction of the T cell immunodeficiency associated with two forms of severe combined immunodeficiencies (SCID) for now more than ten years. Occurrence in some patients of genotoxicity related to retroviral vectors integration close to and transactivation of oncogenes has led to the development of retroviral vectors devoid of its enhancer element. Results of recent trials performed for several forms of PID indeed suggest that their use is both safe and efficacious. It is thus anticipated that their application to the treatment of many more life threatening PID will be developed over the coming years. PMID:25708106

    While most myelodysplastic syndrome/acute myeloid leukemia cases are sporadic, rare familial cases occur and provide some insight into leukemogenesis. The most clearly defined familial cases result from inherited mutations in RUNX1 or CEBPA. Recently, novel germline mutations in GATA2 have been reported. We, therefore, investigated individuals from families with one or more first-degree relatives with myelodysplastic syndrome/acute myeloid leukemia with wild-type RUNX1 and CEBPA, for GATA2 mu...

    Full Text Available Síndromes disexecutivas podem ser observadas em diversas condições neuropsiquiátricas, como transtorno do déficit de atenção e hiperatividade (TDAH, traumatismos cranioencefálicos (TCE ou esquizofrenia, frequentemente se associando à ampla gama de comprometimento, incluindo ambientes familiar, acadêmico e profissional. O objetivo do presente estudo é apresentar três casos de disfunções executivas, nos quais, embora todos os pacientes tenham QI dentro dos limites da normalidade, existe significativo comprometimento social e ocupacional. O primeiro caso apresenta uma jovem que sofreu TCE, com queixas de dificuldades de memória para material novo, além de apatia e diminuição de iniciativa e persistência. O segundo caso versa sobre uma mulher que apresenta problemas desde a educação infantil, com histórico de tratamentos ineficazes e nenhum diagnóstico formal. Segundo relato de informante colateral, há déficits de planejamento, comportamentos antissociais, aversão a gratificações tardias e dificuldades de ativação. O último caso refere-se a indivíduo do sexo masculino, avaliado depois de grave TCE após acidente de carro. Há relato de mudança de comportamento com desinibição, diminuição da persistência e desatenção, relatadas como mais graves do que as apresentadas durante a infância, apesar de desempenho normal em testes de funções executivas. A avaliação de disfunções executivas (do desenvolvimento ou adquiridas pode ser de extrema importância para servir como base de tratamento visando à diminuição de comprometimento nas atividades cotidianas.Dysexecutive syndromes are often observed in several neuropsychiatric conditions, such as attention deficit hyperactivity disorder (ADHD, traumatic brain injuries (TBI or schizophrenia, and usually associate with significant impairments, including familial, academic and professional areas.

    Full Text Available Background: Heyde's syndrome implies an association of calcified aortic stenosis with the high gradient of pressure and angiodysplasic bleeding from the digestive tract. It has been proven that in patients with this syndrome, acquired form of von Willebrand type II A develops. Replacing of aortic valves by artificial ones brings about the spontaneous retreat of coagulation disorder, and the stoppage of the digestive tract bleeding. Case report. We reported two patients with the Heyde's syndrome. In one of the patients the aortic valves were replaced by biologic valves, after which the digestive tract bleeding stopped, while the second patient was treated conservatively due to a high operation risk. Conclusion. Patients with Heyde's syndrome are a complex multidisciplinary problem, thus their adequate treatment requires a team work in order to provide the most rational type of therapy for each patient separately.

  4. Advances of gene therapy for primary immunodeficiencies [version 1; referees: 2 approved

    Full Text Available In the recent past, the gene therapy field has witnessed a remarkable series of successes, many of which have involved primary immunodeficiency diseases, such as X-linked severe combined immunodeficiency, adenosine deaminase deficiency, chronic granulomatous disease, and Wiskott-Aldrich syndrome. While such progress has widened the choice of therapeutic options in some specific cases of primary immunodeficiency, much remains to be done to extend the geographical availability of such an advanced approach and to increase the number of diseases that can be targeted. At the same time, emerging technologies are stimulating intensive investigations that may lead to the application of precise genetic editing as the next form of gene therapy for these and other human genetic diseases.

    2014-01-01

    Full Text Available In Manitoba, Canada, the overall incidence of Severe Combined Immunodeficiency (SCID is three-fold higher than the national average, with SCID overrepresented in two population groups: Mennonites and First Nations of Northern Cree ancestries. T-cell receptor excision circle (TREC assay is being used increasingly for neonatal screening for SCID in North America. However, the majority of SCID patients in Manitoba are T-cell-positive. Therefore it is likely that the TREC assay will not identify these infants. The goal of this study was to blindly and retrospectively perform TREC analysis in confirmed SCID patients using archived Guthrie cards. Thirteen SCID patients were tested: 5 T-negative SCID (3 with adenosine deaminase deficiency, 1 with CD3δ deficiency, and 1 unclassified and 8 T-positive SCID (5 with zeta chain-associated protein kinase (ZAP70 deficiency and 3 with inhibitor of kappa light polypeptide gene enhancer in B-cells, kinase beta (IKKβ deficiency. As a non-SCID patient group, 5 Primary Immunodeficiency Disease (PID patients were studied: 1 T-negative PID (cartilage-hair hypoplasia and 4 T-positive PID (2 common immune deficiency (CID, 1 Wiskott–Aldrich syndrome, and 1 X-linked lymphoproliferative disease. Both patient groups required hematopoietic stem cell transplantation. In addition, randomly-selected de-identified controls (n = 982 were tested. Results: all T-negative SCID and PID had zero TRECs. Low-TRECs were identified in 2 ZAP70 siblings, 1 CID patient as well as 5 preterm, 1 twin, and 4 de-identified controls. Conclusions: TREC method will identify T-negative SCID and T-negative PID. To identify other SCID babies, newborn screening in Manitoba must include supplemental targeted screening for ethnic-specific mutations.

    2011-01-01

    Full Text Available The etiopathology of acquired cholesteatoma has undergone numerous changes over the past 150 years. However, certain facts stand out with clarity. The presence of cytokeratins in acquired cholesteatoma, which are akin to those found in the tympanic membrane and external auditory canal, shows that these are probably the site of origin of acquired cholesteatoma. The cholesteatoma sac also shows its greatest growth at its tympanic membrane attachment into the middle ear. Implantations of squamous epithelium due to trauma or surgery could be another originating factor. The basic pathology is the formation of papillary cones from the tympanic membrane or external auditory canal, which progress from microcholesteatoma to frank cholesteatoma with keratin collections. There is an altered matrix metalloproteinase pathway. Tumor necrosis factor activation with altered wound healing process contributes to the collateral destruction of bone. Trisomy and aneuploidy of chromosome 8 predispose to cholesteatoma formation in affected individuals. In this article, we present the etiopathology of acquired cholesteatoma as it stands today.

A major area of challenge with regards to HIV counseling for clients is disclosure of their HIV status to their partners. The main methods of partner notification are patient referral, provider referral, contract referral, and outreach assistance. The emphasis on a plausible and comprehensive partner referral strategy for widespread positive case detection in resource-limited countries needs to be thought out and developed.Methods: A qualitative study was conducted among newly HIV-positive clients to identify partners for notification and acceptance of referral by their partners. Health service providers working in HIV testing and counseling clinics were also provided with semistructured questionnaires in order to assess their view towards partner notification strategies for clients testing positive for HIV.Results: Fifteen newly diagnosed HIV-positive clients were counseled to provide referral slips to their partners. All clients agreed and took the referral card. However, only eight were willing and actually provided the card to their partners. Five of the eight partners of clients who tested HIV-positive and who were provided with referral cards responded to the referral and were tested for HIV. Three were positive and two were negative. Nine of 11 counselors did not agree to requesting partner locator information from HIV-positive clients for contractual referral and/or outreach assistance. The findings

    Acquired cystic kidney disease (ACKD), also known as acquired renal cystic disease (ARCD,) occurs in patients who are on dialysis for end-stage renal disease. It is generally accepted that ACKD develops as a consequence of sustained uremia and can first manifest even before dialysis is initiated while the patient is still in chronic renal failure. The role of immune suppression, particularly in transplant recipients, in the development of ACKD, is still under investigation. The prevalence of ACKD is directly related to the duration of dialysis and the risk of cancer is directly related to the presence of cysts. Herein we review the current understanding of the pathophysiology and imaging implications of ACKD. (orig.)

    Objective To study the presence of drug resistant mutations of protease and reverse transcriptase among human immunodeficiency virus (HIV)-1 strains isolated from treatment naive HIV/ acquired immune deficiency syndrome (AIDS) patients in Heilongjiang Province of China and to provide the baseline data for starting antiretroviral therapy in this area. Methods The protease and reverse transcriptase gene sequences were amplified by nested-polymerase chain reaction (PCR) and then sequenced. The results were compared to the subtype B consensus amino acid sequence and analyzed with Stanford HIV-db drug resistance sequence interpretation. Results The results showed that HIV strains from 49 patients were classified as subtype B'. No primary mutations associated with protease inhibitor were detected. Some secondary mutations associated with protease inhibitor were detected, which included V77I(91.5%), L63P(76.6%), I93L(74.5%), E35D(61.7%), R57K (19.1%), R41K(10.6%), A71V(8.5%), M36I(8.5%), L10I(6.4%), D60E(6.4%), L89M (4.2%) and G16E(2. 1%). Only one case had a primary mutation M184I that was associated with resistance to reverse transcriptase inhibitors. However, many secondary mutations associated with resistance to reverse transcriptase inhibitors were found, including I135L/T/R/V(81.8%), V106I(22.7%), V179D/E(11.4%), R211K(9.1%), L214F(4.5%), V189I(4.5%) and V108I(2. 3%).Conclusions The prevalence of genotypic anti-HIV drug resistance is very low in treatment naive HIV/AIDS patients in Heilongjiang Province. However, closely monitoring on drug resistance mutation is very important for preventing the development and prevalence of multi-drug resistant or cross drug resistant HIV.%目的 对黑龙江省流行的HIV-1毒株的蛋白酶基因及反转录酶基因进行基因型耐药分析,为开展大规模临床抗病毒治疗提供本底数据.方法 采用套式-PCR法扩增黑龙江省内49例HIV-1感染者及AIDS患者外周血单个核细胞中前病毒cDNA的部分

    2009-01-01

    @@ Worldwide, the hepatitis C virus (HCV) and humanimmunodeficiency virus (HIV) pandemics poseserious threats to global health, currently infecting 130 million and 40 million people respectively. Of those infected with HIV, an estimated 4-12 million are co-infected with HCV. Due to shared risk factors for transmission, co-infection with HIV and HCV is common in China. Liver disease was the second leading cause of death behind acquired immunodeficiency syndrome (AIDS) in co-infected patients. Several studies have confirmed that HIV co-infection accelerates the clinical course of chronic HCV infection and leads to an increased risk of cirrhosis, hepatocellular carcinoma, and decompensated liver disease. While some studies have shown an increased risk of progression to AIDS andAIDS-related death among HIV-HCV positive persons, others found that HCV may not affect the clinical course of HIV infection. The current optimal therapeutic approach to HCV infection in HIV co-infected patients is peg-IFN plus ribavirin but further investigation is ongoing to improve outcomes.

  19. "Primary Immunodeficiencies Inducing EBV-Associated Severe Illnesses "

    Toshio Miyawaki

    2004-06-01

    Full Text Available Epstein-Barr virus (EBV is a ubiquitous human -herpesvirus that infects about 95% of the adult population. The majority of primary infections occurs in early childhood and is generally subclinical; it can cause infectious mononucleosis (IM, which is usually a self-limiting lymphoproliferative disorder. However, infection of EBV occasionally results in severe, often lethal diseases, which include fatal IM, hemophagocytic syndrome, polyclonal lymphoproliferative disorders, and malignant lymphoma. These severe EBV-related illnesses occur secondary to some primary immunodeficiency diseases showing inefficient immune reaction to EBV. One example is X-linked lymphoproliferative disease (XLP, which is caused by mutations in the SLAM-associated protein (SAP gene. The major clinical manifestations of XLP are fulminant IM, malignant lymphoma and dysgammaglobulinemia. Aplastic anemia, virus-associated hemophagocytic syndrome, and vasculitis have also been reported in XLP. We have developed a flow cytometric method using the anti-SAP monoclonal antibody to search for XLP. This clinically useful assay has successfully been used to identify XLP patients in Japan. In this review, clinical and mutational characteristics of XLP in Japan are mainly described. In addition, it is shown that the similar situations to XLP can occur in other primary immunodeficiencies involving T-cell killing function, such as autoimmune lymphoproliferative syndrome caused by Fas gene mutations or familial hemophagocytic lymphohistiocytosis caused by perforin gene mutations. Finally, the EBV-related terrible disease condition, namely chronic active EBV infection, which is common in Asian areas but its genetic background remains to be elucidated, will be toughed on.

Phylogenetic analyses showed that gorillas acquired the simian immunodeficiency virus SIVgor from chimpanzees, and viruses from the SIVcpz/SIVgor lineage have been transmitted to humans on at least four occasions, leading to HIV-1 groups M, N, O, and P. To determine the geographic distribution, prevalence, and species association of SIVgor, we conducted a comprehensive molecular epidemiol...

  11. Strategies for B-cell receptor repertoire analysis in Primary Immunodeficiencies:From severe combined immunodeficiency to common variable immunodeficiency

    2015-04-01

    Full Text Available The antigen receptor repertoires of B and T cells form the basis of the adaptive immune response. The repertoires should be sufficiently diverse to recognize all possible pathogens. However, careful selection is needed to prevent responses to self or harmless antigens. Limited antigen receptor repertoire diversity leads to immunodeficiency, whereas unselected or misdirected repertoires can result in autoimmunity. The antigen receptor repertoire harbors information about abnormalities in many immunological disorders. Recent developments in next generation sequencing allow the analysis of the antigen receptor repertoire in much greater detail than ever before. Analyzing the antigen receptor repertoire in patients with mutations in genes responsible for the generation of the antigen receptor repertoire will give new insights into repertoire formation and selection. In this perspective we describe strategies and considerations for analysis of the naive and antigen selected B-cell repertoires in primary immunodeficiency (PID patients with a focus on severe combined immunodeficiency (SCID and common variable immunodeficiency (CVID.

  13. Clinical applications of gene therapy for primary immunodeficiencies.

    Cicalese, Maria Pia; Aiuti, Alessandro

    2015-04-01

    Primary immunodeficiencies (PIDs) have represented a paradigmatic model for successes and pitfalls of hematopoietic stem cells gene therapy. First clinical trials performed with gamma retroviral vectors (γ-RV) for adenosine deaminase severe combined immunodeficiency (ADA-SCID), X-linked SCID (SCID-X1), and Wiskott-Aldrich syndrome (WAS) showed that gene therapy is a valid therapeutic option in patients lacking an HLA-identical donor. No insertional mutagenesis events have been observed in more than 40 ADA-SCID patients treated so far in the context of different clinical trials worldwide, suggesting a favorable risk-benefit ratio for this disease. On the other hand, the occurrence of insertional oncogenesis in SCID-X1, WAS, and chronic granulomatous disease (CGD) RV clinical trials prompted the development of safer vector construct based on self-inactivating (SIN) retroviral or lentiviral vectors (LVs). Here we present the recent results of LV-mediated gene therapy for WAS showing stable multilineage engraftment leading to hematological and immunological improvement, and discuss the differences with respect to the WAS RV trial. We also describe recent clinical results of SCID-X1 gene therapy with SIN γ-RV and the perspectives of targeted genome editing techniques, following early preclinical studies showing promising results in terms of specificity of gene correction. Finally, we provide an overview of the gene therapy approaches for other PIDs and discuss its prospects in relation to the evolving arena of allogeneic transplant. PMID:25860576

    2013-01-01

    Full Text Available Background: From the moment scientists identified Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS, social responses of fear, denial, stigma, and discrimination have accompanied the epidemic. Aims: To assess the rate of disclosure of HIV serostatus, reactions by the HIV/AIDS patients and their spouse, and discrimination faced by the patients. Methods: The present cross-sectional study was conducted at Antiretroviral Therapy (ART center of a rural tertiary care hospital, situated in Marathawada region of Maharashtra state from November 2008 to October 2010. Totally, 801 HIV-positive patients coming to ART center for treatment were included after ensuring confidentiality and taking informed consent. A preformed questionnaire was used to enquire about reaction after diagnosis, disclosure, and discrimination faced by the patients. The data analyzed using descriptive statistics and Chi-square test. Results: The most common immediate reaction by the HIV patients after getting diagnosed as seropositive was fear (593, 74.03% followed by depression (385, 48.06% and suicidal thoughts (98, 12.25%. Out of 801 patients, 769 (96% had spouse and of these maximum number of patients (653, 84.92% had disclosed HIV status to their spouses. Most common immediate reaction by spouse after disclosure was crime (324, 42.13% followed by horror (294, 38.23% and anger (237, 36.29%. Maximum number of patients were discriminated by friends (120, 71.01% followed by discrimination at workplace (49, 67.12%, by neighbors (32, 56.14%, and by relatives (53, 43.80%. Conclusion: Male positives were granted greater acceptance, care, and support by their spouses. More percentage of females discriminated by neighbors, relatives, and friends and at workplace which might be due to factors like customs, morals, and taboos.

    Full Text Available Abstract Background Although, in South Korea, human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS keeps increasing and tuberculosis(TB burden is still significant, there have been few reports on TB/HIV cases. In this study, we investigated the burden and characteristics of TB/HIV patients in South Korea, an area with intermediate burden of TB and a low prevalent area with HIV/AIDS. Methods We identified patients with TB and cases with HIV between January 1 2001 and December 31 2005, from nationwide reporting system (TBnet and HIV/AIDS registry through an electronic record linkage method. A questionnaire survey was also conducted and determined the rate of diagnosis of HIV among TB cases in public health units in 2005. Results The number of cases with both HIV and TB was 137 (0.07% among 197,562 TB cases and the newly detected TB/HIV cases per 100,000 population was increasing annually: 2001, 0.025; 2002, 0.031; 2003, 0.025; 2004, 0.071; 2005, 0.095. Males between 20 and 59 years of age accounted for 87.6% of TB/HIV patients. Compared with patients with TB alone, those with TB/HIV had a higher percentage of extrapulmonary TB (8.0% vs 19.0%; p Conclusions The prevalence rate of TB/HIV patients is still low but increasing in South Korea. Physicians should consider performing HIV tests among TB patients, especially in higher-risk groups, such as young males with extrapulmonary TB in South Korea.

    Full Text Available Bacterial lung infection is the leading cause of morbidity and mortality of patients with human immunodeficiency virus (HIV/acquired immunodeficiency syndrome (AIDS. HIV infection causes immune system dysfunction, which is manifested by decreased cluster of differentiation 4 (CD4 cell counts. The purpose of this study was to determine the correlation between CD4 cell counts and the type of bacteria that caused lung infection from cultured washing of bronchoalveolar lavage in HIV patients in Dr. Hasan Sadikin Hospital Bandung. This was an observational analytic study with a cross-sectional design. Subjects were collected from November 2011 to October 2013 in Internal Departement Dr. Hasan Sadikin Hospital Bandung. There were 39 subjects enrolled with the average age of patients was 32 years. The median CD4 cell counts was 18 (range, 0–190 cell/mm3. The type of gram-negative rods bacteria was 29/39 samples and gram-positive cocci was 10/39 samples. Most species were Pseudomonas aeruginosa 11/39 samples, Klebsiella pneumoniae 11/39 samples and Streptococcus viridans 10/39 samples. Statistical analysis based on a point biserial correlation showed weak (r=0.232 and no significant correlation between CD4 cell counts and the type of bacteria (p>0.05. The weak correlation was the smaller the number of CD4 cell counts, the greater possibility of the gram-negative rod bacteria being the cause of the infection. This study concluded that there is only a weak and no correlation between the number of CD4 cell counts and the type of bacteria causing the lung infection obtained from bronchoalveolar lavage in patients with HIV in Dr. Hasan Sadikin Hospital Bandung.

    2010-03-01

    Full Text Available Pediatric immunology came into sight in the second half of 20th century, when pediatricians and basic immunologists began to give attention to diagnosis and treatment of children with primary immunodeficiency diseases (PIDs. Understanding the genetic and mechanistic basis of PIDs provides unique insight into the functioning of the immune system. By progress in basic and clinical immunology, many infrastructural organizations and academic centers have been established in many countries worldwide to focus on training and research on the immune system and related disorders. Along with progress in basic and clinical immunology in the world, pediatric immunology had a good progress in Iran during the last 33-year period. Now, patients with PIDs can benefit from multidisciplinary comprehensive care, which is provided by clinical immunologists in collaboration with other specialists. Patients with history of recurrent and/or chronic infections suggestive of PIDs are evaluated by standard and research-based testing and receive appropriate treatment. The progress in PIDs can be described in three periods. Development of training program for clinical fellowship in allergy and immunology, multidisciplinary and international collaborative projects, primary immunodeficiency diseases textbooks, meetings on immunodeficiency disorders, improvement in diagnosis and treatment, and construction of Iranian primary immunodeficiency association, Students research group for immunodeficiencies, Iranian primary immunodeficiency registry, and the immunological societies and centers were the main activities on PIDs during these years. In this article, we review the growth of modern pediatric immunology and PIDs status in Iran.

  2. Guidelines for prevention of hospital acquired infections

    Yatin Mehta

    2014-01-01

    Full Text Available These guidelines, written for clinicians, contains evidence-based recommendations for the prevention of hospital acquired infections Hospital acquired infections are a major cause of mortality and morbidity and provide challenge to clinicians. Measures of infection control include identifying patients at risk of nosocomial infections, observing hand hygiene, following standard precautions to reduce transmission and strategies to reduce VAP, CR-BSI, CAUTI. Environmental factors and architectural lay out also need to be emphasized upon. Infection prevention in special subsets of patients - burns patients, include identifying sources of organism, identification of organisms, isolation if required, antibiotic prophylaxis to be used selectively, early removal of necrotic tissue, prevention of tetanus, early nutrition and surveillance. Immunodeficient and Transplant recipients are at a higher risk of opportunistic infections. The post tranplant timetable is divided into three time periods for determining risk of infections. Room ventilation, cleaning and decontamination, protective clothing with care regarding food requires special consideration. Monitoring and Surveillance are prioritized depending upon the needs. Designated infection control teams should supervise the process and help in collection and compilation of data. Antibiotic Stewardship Recommendations include constituting a team, close coordination between teams, audit, formulary restriction, de-escalation, optimizing dosing, active use of information technology among other measure. The recommendations in these guidelines are intended to support, and not replace, good clinical judgment. The recommendations are rated by a letter that indicates the strength of the recommendation and a Roman numeral that indicates the quality of evidence supporting the recommendation, so that readers can ascertain how best to apply the recommendations in their practice environments.

  3. Intercontrole acquiring by Framatome

    The Framatome group, as the worldwide leader in nuclear power plant construction, has reinforced his competences in nuclear services thanks to the acquiring of the Intercontrole company, specialized in non-destructive testing in nuclear and industrial environments. After a presentation of the functioning principle and of the safety aspects of a PWR reactor, this press dossier presents in a first part the role of nuclear services and in particular of non-destructive testing in nuclear power plants (in-service inspection, regulatory aspects, testing processes). This part is illustrated with some examples of inspection performed on some components of the primary coolant loop (steam generators, reactor vessel, pressurizer, pipes, primary pumps). A second part presents the technical centres and units of Framatome in charge of performing non-destructive inspections, while a third part describes the industrial policy and strategy of the group in this domain (market of nuclear park maintenance in France, in the USA and worldwide, creation of the 'inspection and control' centre of Framatome). A last part presents the activities of the Intercontrole company and of its daughter companies with some examples of actions realized in the nuclear and natural gas domains. (J.S.)

  4. Radiosensitive severe combined immunodeficiency disease.

    Dvorak, Christopher C; Cowan, Morton J

    2010-02-01

    Inherited defects in components of the nonhomologous end-joining DNA repair mechanism produce a T-B-NK+ severe combined immunodeficiency disease (SCID) characterized by heightened sensitivity to ionizing radiation. Patients with the radiosensitive form of SCID may also have increased short- and long-term sensitivity to the alkylator-based chemotherapy regimens that are traditionally used for conditioning before allogeneic hematopoietic cell transplantation (HCT). Known causes of radiosensitive SCID include deficiencies of Artemis, DNA ligase IV, DNA-dependent protein kinase catalytic subunit, and Cernunnos-XLF, all of which have been treated with HCT. Because of these patients' sensitivity to certain forms of chemotherapy, the approach to donor selection and the type of conditioning regimen used for a patient with radiosensitive SCID requires careful consideration. Significantly more research needs to be done to determine the long-term outcomes of patients with radiosensitive SCID after HCT and to discover novel nontoxic approaches to HCT that might benefit those patients with intrinsic radiosensitivity and chemosensitivity as well as potentially all patients undergoing an HCT.

  5. MRI of fetal acquired brain lesions

    Acquired fetal brain damage is suspected in cases of destruction of previously normally formed tissue, the primary cause of which is hypoxia. Fetal brain damage may occur as a consequence of acute or chronic maternal diseases, with acute diseases causing impairment of oxygen delivery to the fetal brain, and chronic diseases interfering with normal, placental development. Infections, metabolic diseases, feto-fetal transfusion syndrome, toxic agents, mechanical traumatic events, iatrogenic accidents, and space-occupying lesions may also qualify as pathologic conditions that initiate intrauterine brain damage. MR manifestations of acute fetal brain injury (such as hemorrhage or acute ischemic lesions) can easily be recognized, as they are hardly different from postnatal lesions. The availability of diffusion-weighted sequences enhances the sensitivity in recognizing acute ischemic lesions. Recent hemorrhages are usually readily depicted on T2 (*) sequences, where they display hypointense signals. Chronic fetal brain injury may be characterized by nonspecific changes that must be attributable to the presence of an acquired cerebral pathology. The workup in suspected acquired fetal brain injury also includes the assessment of extra-CNS organs that may be affected by an underlying pathology. Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images

  8. Translocations (5;17) and (7;17) in patients with de novo or therapy-related myelodysplastic syndromes or acute nonlymphocytic leukemia. A possible association with acquired pseudo-Pelger-Hut anomaly and small vacuolated granulocytes

    Twelve patients [two with de novo myelodysplastic syndrome (MDS), four with secondary MDS, five with de novo acute nonlymphocytic leukemia (ANLL), one with secondary ANLL] showed a 17p deletion resulting from translocations involving 17p: t(5;17)(p11;p11) in four cases, t(7;17)(p11;p11) in six cases, complex (5;17)(q23;p12) translocation with dicentric chromosome in one case, and t(17;?)(p11-12;?) in the remaining patient. All these structural anomalies were observed in hypodiploid clones associated with total or partial monosomy of chromosomes 5 and 7 (12 cases), monosomy 12 (five cases), monosomy 3 (four cases), and monosomy 4 (three cases). Median survival was only 3.3 months (range 3 days to 8 months). Striking features were observed in bone marrow mature granulocytes: all but one case had a pseudo-Pelger-Hut anomaly in a significant number of granulocytes, and eight patients had granulocytes with reduced size and clear cytoplasmic vacuoles. Careful cytological review of 51 patients with MDS or ANLL and various cytogenetic anomalies was performed for comparison: vacuolated granulocytes were a very uncommon finding. On the other hand, eight patients had a pseudo-Pelger-Hut anomaly, which correlated significantly with total monosomy 17 in these patients. A possible correlation between cytological anomalies and cytogenetic data is discussed, and the role of 17p in the nuclear segmentation of granulocytes is stressed

  10. Effect of Probiotic Bacteria on Microbial Host Defense, Growth, and Immune Function in Human Immunodeficiency Virus Type-1 Infection

    Stig Bengmark

    2011-12-01

    Full Text Available The hypothesis that probiotic administration protects the gut surface and could delay progression of Human Immunodeficiency Virus type1 (HIV-1 infection to the Acquired Immunodeficiency Syndrome (AIDS was proposed in 1995. Over the last five years, new studies have clarified the significance of HIV-1 infection of the gut associated lymphoid tissue (GALT for subsequent alterations in the microflora and breakdown of the gut mucosal barrier leading to pathogenesis and development of AIDS. Current studies show that loss of gut CD4+ Th17 cells, which differentiate in response to normal microflora, occurs early in HIV-1 disease. Microbial translocation and suppression of the T regulatory (Treg cell response is associated with chronic immune activation and inflammation. Combinations of probiotic bacteria which upregulate Treg activation have shown promise in suppressing pro inflammatory immune response in models of autoimmunity including inflammatory bowel disease and provide a rationale for use of probiotics in HIV-1/AIDS. Disturbance of the microbiota early in HIV-1 infection leads to greater dominance of potential pathogens, reducing levels of bifidobacteria and lactobacillus species and increasing mucosal inflammation. The interaction of chronic or recurrent infections, and immune activation contributes to nutritional deficiencies that have lasting consequences especially in the HIV-1 infected child. While effective anti-retroviral therapy (ART has enhanced survival, wasting is still an independent predictor of survival and a major presenting symptom. Congenital exposure to HIV-1 is a risk factor for growth delay in both infected and non-infected infants. Nutritional intervention after 6 months of age appears to be largely ineffective. A meta analysis of randomized, controlled clinical trials of infant formulae supplemented with Bifidobacterium lactis showed that weight gain was significantly greater in infants who received B. lactis compared to

There is also a critical need for the development of culturally tailored combination HIV prevention interventions that not only incorporate evidence-based behavioral and biomedical approaches (eg, microbicides, pre-exposure prophylaxis, female-initiated barrier methods but also take into account the risk environment at the physical, social, economic and political levels. Ultimately, this approach will have a significant impact on reducing HIV infections among drug-using women with histories of partner violence.Keywords: human immunodeficiency virus, acquired immune deficiency syndrome, interventions, drugs, women, partner violence, gender-based inequalities

  14. The Italian Network of Primary Immunodeficiencies

    Alessro Plebani

    2004-12-01

    Full Text Available Primary immunodeficiencies are rare diseases, characterized by an increased susceptibility to infections. Early diagnosis and appropriate treatment are critical for reducing morbidity and mortality. Given the rarity of these diseases, the awareness of these disorders by physicians is often insufficient, leading to delayed diagnosis and inappropriate treatment which are the major causes of severe long term complications. In an attempt to address and resolve these problems an Italian Network on primary immunodeficiencies has been established with the aim to increase the awareness of these disorders among physicians and to provide the best clinical assistance to all patients on the national territory.

  15. A rare complication of Ramsey Hunt Syndrome: Sınus vein thrombosis

    Ramiz Ahmedov

    2011-03-01

    Full Text Available Ramsay-Hunt Syndrome (RHS is a rare affection characterized by peripheral facial paralysis (PFP, skin eruption in the auricular canal and cochleovestibular symptoms. It is produced by varicella-zoster virus(VZV reactivation at the geniculate ganglia. In elderly and immunocompromised individuals, the virus may reactivate to produce shingles (zoster. After zoster resolves, many elderly patients experience postherpetic neuralgia. Uncommonly, VZV can spread to large cerebral arteries to cause a spectrum of large-vessel vascular damage, ranging from vasculopathy to vasculitis, with stroke. In immunocompromised individuals, especially those with cancer or acquired immunodeficiency syndrome, deeper tissue penetration of the virus may occur (as compared with immunocompetent individuals, with resultant myelitis, small-vessel vasculopathy, ventriculitis, and meningoencephalitis. The polymerase chain reaction (PCR analysis of cerebrospinal fluid remains the mainstay for diagnosing the neurologic complications of VZV during life. We report a case of Ramsay Hunt syndrome complicated with cerebral venous thrombosis. Patient received treatment with acyclovir and anticoagulation. Early treatment with acyclovir therapy and anticoagulation could improve the recovery rate of facial nerve palsy and sinus vein thrombosis.

    Deĭkina, O N; Mishin, V Iu; Demikhova, O V

    2007-01-01

    The purpose of this investigation was to enhance the efficiency of differential diagnosis of pneumonia and pulmonary tuberculosis. A hundred and fifty-nine adult patients were examined. These included 78 patients with pulmonary tuberculosis and 81 with community-acquired p neumonia. The clinical features of infiltrative pulmonary tuberculosis (n = 48) and mild community-acquired pneumonia (n = 51) were compared. The course of caseous pneumonia (n = 30) was compared with that of moderate and severe community-acquired pneumonia (n = 30). Significant differences in the manifestations of the intoxication and bronchopulmonary syndrome were not found in patients with community-acquired pneumonia and infiltrative pulmonary tuberculosis. Physical studies showed that in patients with community-acquired pneumonia, moist rale (54.9%) and crepitation (11.8%) were prevalent, but in those with infiltrative tuberculosis rale was absent in 60.4% of cases and the pattern of respiration was unchanged in 79.2%. Chest X-ray studies indicated that in patients with community-acquired pneumonia, lower lobar inflammatory changes were predominant in 62.8% of cases whereas in those with infiltrative pulmonary tuberculosis the process was mainly bilateral (43.8%) with the presence of destructive changes (83.3%) and bronchogenic dissemination (66.7%). In patients with caseous pneumonia, the intoxication syndrome was more significant than in those with severe community-acquired pneumonia. Chest X-ray studies demonstrated that in patients with caseous pneumonia, specific changes were bilateral with the involvement of 2 lobes or more, with destruction and bronchogenic dissemination while in those with community-acquired pneumonia, the pulmonary processes were predominantly bilateral (76.6%) at the lower lobar site (36.7%).

  17. Gene therapy for primary immunodeficiencies: current status and future prospects.

    Qasim, Waseem; Gennery, Andrew R

    2014-06-01

    Gene therapy using autologous haematopoietic stem cells offers a valuable treatment option for patients with primary immunodeficiencies who do not have access to an HLA-matched donor, although such treatments have not been without their problems. This review details gene therapy trials for X-linked and adenosine deaminase (ADA)-deficient severe combined immunodeficiency (SCID), Wiskott-Aldrich syndrome (WAS) and chronic granulomatous disease (CGD). X-linked SCID was chosen for gene therapy because of previous 'natural' genetic correction through a reversion event in a single lymphoid precursor, demonstrating limited thymopoiesis and restricted T-lymphocyte receptor repertoire, showing selective advantage of progenitors possessing the wild-type gene. In early studies, patients were treated with long terminal repeats-intact gamma-retroviral vectors, without additional chemotherapy. Early results demonstrated gene-transduced cells, sustained thymopoiesis, and a diverse T-lymphocyte repertoire with normal function. Serious adverse effects were subsequently reported in 5 of 20 patients, with T-lymphocyte leukaemia developing, secondary to the viral vector integrating adjacent to a known oncogene. New trials using self-inactivating gamma-retroviral vectors are progressing. Trials for ADA-SCID using gamma-retroviral vectors have been successful, with no similar serious adverse effects reported; trials using lentiviral vectors are in progress. Patients with WAS and CGD treated with early gamma-retroviral vectors have developed similar lymphoproliferative adverse effects to those seen in X-SCID--current trials are using new-generation vectors. Targeted gene insertion using homologous recombination of corrected gene sequences by cellular DNA repair pathways following targeted DNA breakage will improve efficacy and safety of gene therapy. A number of new techniques are discussed. PMID:24848753

    2014-07-01

    Full Text Available Primary immunodeficiencies (PID are inherited disorders which one or several components of immune system are decreased or missing or of non-appropriate function. These diseases affect the development, function or morphology of the immune system. The group of primary immunodeficiencies comprises more than 200 different disorders and syndromes and the number of newly recognized and revealed deficiencies is still increasing. Their clinical presentation and complications depends on the type of defects and there is a great variability in the relationship between genotypes and phenotypes. A variation of clinical presentation across various age categories is also presented and children could widely differ from adult patients with PID. Respiratory symptoms and complications present a significant cause of morbidity and also mortality amongst patients suffering from different forms of PIDs and they are observed both in children and adults. They can affect primarily either upper airways (e.g. sinusitis, otitis media or lower respiratory tract (e.g. pneumonia, bronchitis, bronchiectasis, interstitial lung diseases. The complications from lower respiratory tract are usually considered to be more important and also more specific for PIDs and they determinate patients’ prognosis. The spectrum of the causal pathogens usually demonstrates typical pattern characteristic for each PID category. The respiratory signs of PIDs can be divided into infectious (upper and lower respiratory tract infections and complications and non-infectious (interstitial lung diseases, bronchial abnormalities – especially bronchiectasis, malignancies, benign lymphoproliferation. Early diagnosis and appropriate therapy can prevent or at least slow down the development and course of respiratory complications of PIDs.

  20. The Prevalence of Different Human Immunodeficiency Virus Transmission Routes and Knowledge about AIDS in Infected People with HIV in Sirjan

    Mahin Behzadpour

    2012-06-01

    Full Text Available Background & Objective: The immune system of Patients with Acquired Immune Deficiency Syndrome (AIDS is weekend because of Human immunodeficiency virus (HIV infection, and they become vulnerable to several opportunistic and non-opportunistic pathogens and different carcinomas. IV drug abuse, sexual contact, occupational transmission, blood transfusion and maternal-fetal transmission are well known transmission routes for HIV infection. This study was under taken to investigate the prevalence of HIV transmission routs in the HIV infected population of Sirjan, and their knowledge about the disease, in order to plan better preventive strategies. Materials & Methods: A cross sectional study was planned. During a 6-month period in 2010, all of the HIV infected people in Sirjan (old and new cases who had a file at the consultation center for high risk behavior, completed a valid and reliable questionnaire. Results: The definite route of transmission was not clear in any of the patients because they had more than one suspicious route. Injected drug abusers were the most common (88.4% followed by those who got tattoos (79.1%, invasive therapeutic procedures, dentistry, surgery and endoscopy (56.1%, high risk sexual behavior (62.8%, bloodletting (9.3%, injuries in the barbershop (9.3% and blood transfusion (2.3%. Conclusion: All of the HIV infected cases in Sirjan were involved with several high risk behaviors, but the major route of transmission, similar to other parts of the country was injected drug abuse. Educational programs for prevention of AIDS should be followed seriously and special attention should be paid to groups with multiple high risk behaviors.

In this study we used the polymerase chain reaction (PCR to detect proviral DNA of feline immunodeficiency virus on the blood and tissue samples from cats with a clinical diagnosis of immunodeficiency. The PCR primers were used to amplify the gag gene, which is conserved among different isolates. From 40 samples analyzed, 15 were positive and 4 of them were submitted to hybridization to confirm the specificity of the amplified fragments. These results confirm the

  4. Myasthenic syndromes.

    Farrugia, M E

    2011-03-01

    The neuromuscular junction is vulnerable to autoimmune attack both at the pre-synaptic nerve terminal and at the post-synaptic muscle membrane. Antibodies directed to the nicotinic acetylcholine receptor at the muscle surface are the cause of myasthenia gravis in the majority of cases. Myasthenia gravis is an acquired condition, characterised by weakness and fatigability of the skeletal muscles. The ocular muscles are commonly affected first, but the disease often generalises. Treatment includes symptom control and immunosuppression. The thymus gland plays an important role in the pathogenesis of myasthenia gravis and thymectomy is indicated in certain subgroups. Lambert-Eaton myasthenic syndrome is associated with antibodies directed to the voltage-gated calcium channel antibodies at the pre-synaptic nerve terminal. It is an acquired condition and, in some cases, may be paraneoplastic, often secondary to underlying small cell lung carcinoma. Clinical presentation is distinct from myasthenia gravis, with patients often first presenting with lower limb muscle fatigability and autonomic symptoms. Congenital myasthenic syndromes are inherited neuromuscular disorders due to mutations in proteins at the neuromuscular junction. Various phenotypes exist depending on the protein mutation. Treatment is directed towards symptom control and immunosuppression is not indicated. PMID:21365067

  7. Burden Among Caregivers of Children Living with Human Immunodeficiency Virus in North India

    Chauhan, Ramesh Chand; Rai, Sanjay Kumar; Kant, Shashi; Lodha, Rakesh; Kumar, Nand; Singh, Neelima

    2016-01-01

    Background: Due to wider access to and free antiretroviral therapy (ART) program, the number of children dying due to acquired immune deficiency syndrome (AIDS)-related causes has declined and the nature and duration of human immunodeficiency virus (HIV)/AIDS caregiving has also dramatically altered. The care of children living with HIV/AIDS (CLHA) places a significant additional burden on the caregivers. Aims: This study was conducted to assess the perceived burden among caregivers of children living with HIV in North India. Materials and Methods: A hospital-based cross-sectional study among 156 CLHA-caregiver dyads in North India was conducted from June 2010 to May 2011. Data were collected by using a pretested structured interview schedule. The caregiver burden was measured with a 36-item scale adapted from Burden Assessment Schedule of Schizophrenia Research Foundation (BASS). Child characteristics, caregiver characteristics, caregiving burden, the knowledge of caregivers, and issues related to health care, nutrition, education, and psychological aspects were studied. Results: Caregivers had a mean age of 35.9 ± 10.2 years. Women accounted for over three-fourth (76.9%) of the caregivers. Nearly two-third of them (65.4%) reported as living with HIV. The mean caregiver burden score was 68.7 ± 2.9. A majority of the caregivers reported either low or moderate burden. Standardized percentage score was high in the domains of physical and mental health, external support, patients’ behavior, and caregivers’ strategy and seemed to be comparatively less in the other domains such as support of the patient and taking responsibility. Conclusions: Caring of children is a universal practice but there is a need of special care for children living with HIV. The majority of caregivers who were usually the mothers perceived the burden and need to be assisted in caring for the child. Stigma and discrimination with HIV infection further increased the burden as caregivers did

    The antigen receptor repertoires of B and T cells form the basis of the adaptive immune response. The repertoires should be sufficiently diverse to recognize all possible pathogens. However, careful selection is needed to prevent responses to self or harmless antigens. Limited antigen receptor repertoire diversity leads to immunodeficiency, whereas unselected or misdirected repertoires can result in autoimmunity. The antigen receptor repertoire harbors information about abnormalities in many ...

    Full Text Available Background. In general, primary immunodeficiency diseases (PIDs are underdiagnosed in most countries. The objective of this study was to describe the frequency and clinical spectrum of PID in the most important tertiary hospitals in our region. Methods. An observational, cross-sectional, with retrospective chart, review study was conducted. A total of 26 patients were included and grouped according to the updated classification of PIDs. Results. PIDs spectra were as follows: predominantly antibody deficiency diseases were the most common category (65.38%, followed by other well-defined immunodeficiency syndromes (11.55%, congenital defects of phagocyte number and/or function (7.69%, complement deficiencies (3.85%, combined T- and B-cell immunodeficiencies (3.85%, and defects in innate immunity (3.85%. The mean time elapsed from the onset of symptoms to the reference and diagnosis by a tertiary hospital was of 4.65 ± 6.95 years. Conclusions. Predominant antibody deficiency disease was the most common group of PIDs, agreeing with international reports. Awareness of underdiagnosis by physicians is crucial for a prompt diagnosis and treatment, which in turn should improve the quality of life among patients with PIDs.

    2015-01-01

    that the pupils were encouraged to use their senses: listen to things frying, touch the meat to check if it was done and taste the food in the process of seasoning it. But while some children learned what the teachers expected: to produce well tasting food, others learned to cook very salty and hot food...... appreciated by the group of boys, and others again learned to stick with their idiosyncrasies when pressured by the teacher. Conclusions: Children were acquiring taste in the home economic lessons, but not only the kind of tastes that the teacher had planned for. This leads to reflections on the very complex...... process of taste acquiring and to a call for further research into taste acquiring in complex real life contexts as home economics lessons....

    Full Text Available The Brazilian variant of human immunodeficiency virus type 1 (HIV-1 subtype B, (serotype B"-GWGR, has a tryptophan replacing the proline in position 328 the HIV-1 envelope. A longer median time period from infection to acquired immunodeficiency syndrome (AIDS for serotype B (B"-GWGR infected subjects compared to the B-GPGR US/European strain was reported. In a cohort study, in São Paulo city, 10 B"-GWGR patients had a statistically significant increased avidity of the anti-V3 antibodies, from 79% ± 33% to 85% ± 75%, versus from 48% ± 59% to 32% ± 17% for the 10 B-GPGR subjects (p = 0.02. The T CD4+ cells showed a mean increase of + 0.45 cells/month for the B-GPGR subjects and for B"-GWGR the slope was + 1.24 cells/month (p = 0.06, for 62 and 55 months of follow up, respectively. RNA plasma viral load decreased from 3.98 ± 1.75 to 2.16 ± 1.54 log10 in the B"-GWGR group while B-GPGR patients showed one log10 reduction in viral load from 4.09 ± 0.38 to 3.17 ± 1.47 log10 over time (p = 0.23, with a decreasing slope of 0.0042 ± log10,/month and 0.0080 ± log10/month, for B-GPGR and B"-GWGR patients, respectively (p = 0.53. Neither group presented any AIDS defining events during the study, according to Center for Diseases Control criteria. Although the sample size is small, these results may indicate that differences in the pathogenicity of the 2 HIV-1 B serotypes which co-circulate in Brazil may be correlated to the avidity of anti-V3 antibodies.

    Persons infected with the human immunodeficiency virus are prone to the development of many fungal diseases. Normal hosts with intact immunity usually recover from infection by these less-invasive fungi. In persons with compromised T-cell-mediated immunity, however, widespread dissemination from a pulmonary focus occurs. In this review, we discuss the epidemiology, clinical manifestations, diagnosis, and treatment of the three major North American mycoses, histoplasmosis, blastomycosis, and c...

    Since the original description of X-linked agammaglobulinemia in 1952, the number of independent primary immunodeficiency diseases (PIDs) has expanded to more than 100 entities. By definition, a PID is a genetically determined disorder resulting in enhanced susceptibility to infectious disease. Despite the heritable nature of these diseases, some PIDs are clinically manifested only after prerequisite environmental exposures but they often have associated malignant, allergic, or autoimmune man...

    Full Text Available Malignant syphilis or Lues maligna, commonly reported in the pre-antibiotic era, has now seen a resurgence with the advent of human immunodeficiency virus (HIV. Immunosuppression and sexual promiscuity set the stage for this deadly association of HIV and Treponema pallidum that can manifest atypically and can prove to cause diagnostic problems. We report one such case in a 30-year-old female who responded favorably to treatment with penicillin.

    Full Text Available Background: Psychiatric morbidity in human immunodeficiency virus (HIV patients is being studied all over the world. There is paucity of Indian literature particularly in asymptomatic HIV individuals. Aim: The aim of the following study is to establish the prevalence and the determinants of psychiatric morbidity in asymptomatic HIV patients. Materials and Methods: A cross-sectional study was undertaken to assess psychiatric morbidity as per ICD-10 dacryocystorhinostomy criteria in 100 consecutive asymptomatic seropositive HIV patients and an equal number of age, sex, education, economic and marital status matched HIV seronegative control. All subjects were assessed with the general health questionnaire (GHQ, mini mental status examination, hospital anxiety and depression scale (HADS and sensation seeking scale (SSS and the scores were analyzed statistically. Results: Asymptomatic HIV positive patients had significantly higher GHQ caseness and depression but not anxiety on HADS as compared to HIV seronegative controls. On SSS asymptomatic HIV seropositive subjects showed significant higher scores in thrill and adventure seeking, experience seeking and boredom susceptibility as compared to controls. HIV seropositive patients had significantly higher incidence of total psychiatric morbidity. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. Conclusion: Psychiatric morbidity is higher in asymptomatic HIV patients when compared to HIV seronegative controls. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. High sensation seeking and substance abuse found in HIV seropositive patients may play a vital role in engaging in high-risk behavior resulting in this dreaded illness.

  9. The Effect of IVIG on Superoxide Generation in Primary Humoral Immunodeficiencies

    Full Text Available Primary antibody deficiency (common variable immunodeficiency, Hyper IgM, X-linked agammaglobulinemia and selective Ig A deficiency is a group of heterogeneous diseases characterized by defective antibody production. In primary hypogammaglobulinemias, particularly in patients with common variable immunodeficiency there is an increased generation of reactive oxygen species from monocytes which may be important for both immunopathogenesis and clinical manifestations. The generation of toxic oxygen metabolites may contribute to inflammation and tissue damage associated with phagocytic infiltration, and play role in the pathogenesis of malignancies, autoimmune disorders, acute and chronic pulmonary diseases seen in these patients. In primary immunodeficiencies and functional antibody deficiencies, IVIG act as replacement therapy and several mechanisms of IVIG action have been postulated. In vitro studies with human granulocytes showed stimulation of respiratory burst and promotion of bacterial killing by IVIG. In adult patients with primary humoral immunodeficiency, treated with IVIG showed that IVIG does not affect superoxide generation. We investigated superoxide generation from PMNL in 35 children with hyper IgM syndrome, XLA, CVID and IgA deficiency and 13 healthy children. We also explored the effect of IVIG administration on superoxide generation from granulocytes, white cell count, absolute neutrophil count, absolute lymphocyte count and quantitative CRP levels. There was a substantial increase in superoxide generation from PMNL in patients with XLA, CVID and IgA deficiency. Comparison of the superoxide generation before, 24 hours and one week after IVIG treatment showed no difference. In patients with CVID, quantitative CRP levels before and 24 hours after IVIG revealed significant difference. Other parameters were not changed. It can be concluded that enhanced superoxide generation in patients with XLA, CVID, Ig A deficiency may result from

  10. Human normal immunoglobulin in the treatment of primary immunodeficiency diseases

    Wood P

    2012-04-01

    Full Text Available Philip WoodSt James University Hospital, Leeds, United KingdomAbstract: The primary antibody deficiency syndromes are a rare group of disorders that can present at any age, and for which delay in diagnosis remains common. Replacement therapy with immunoglobulin in primary antibody deficiencies increases life expectancy and reduces the frequency and severity of infection. Higher doses of immunoglobulin are associated with reduced frequency of infection. Late diagnosis and delayed institution of immunoglobulin replacement therapy results in increased morbidity with a wide variety of organ-specific complications and increased mortality. Risks of immunoglobulin therapy are minimized by modern manufacturing processes, although patients can experience both immediate and delayed adverse reactions, and concerns remain over the transmission of prions in plasma. Immunoglobulin therapy leads to improvements in overall quality of life, and many of the improvements relate to reduced infection rates and fear of future infections, strongly suggesting that the immunoglobulin therapy itself is the major factor in this improvement. There are limited data on the economic benefits of immunoglobulin therapy, with the fluctuating costs of immunoglobulins making comparison between different studies difficult. However, estimates suggest that early intervention with immunoglobulin replacement compares favorably with prolonged therapy for other more common chronic diseases.Keywords: antibody deficiency, immunoglobulin therapy, common variable immunodeficiency

    Full Text Available In a litter of seven Dachshund puppies, one subject was stillborn and six presented with diffuse skin infections characterized by dermatitis, abscessation, pustules, crusts and ulcers. Two of the puppies were referred for further evaluation. One male puppy was referred at four months of age and a sister litter mate was referred two months later. A complete blood count, biochemical and histological examination were performed on these puppies to identify the pathologic process. Clinical, biochemical, haematological and histological evaluation of subjects. This report characterizes quantitative and qualitative haematological abnormalities in two puppies that resulted in a diagnosis of dysmyelopoiesis. The existence of a familial immunodeficiency syndrome was speculated. This is the first report of such a syndrome in Dachshund puppies.

    Full Text Available A 30-year -old man was seen for acquired anhidrosis. There was no systemic disease. Vasomotor functions were normal. Biopsy showed normal sweat glands and ducts. Intravenous injection of neostigmine could produce profuse sweating on the face, trunk and arms. The disorder is likely to be due to a peripheral dysautonomia selectively affecting the sudomotor function.

    Full Text Available From 1992 to 1995 we studied 232 (69% male, 87% Caucasian anti-human immunodeficiency virus (anti-HIV positive Brazilian patients, through a questionnaire; HIV had been acquired sexually by 50%, from blood by 32%, sexually and/or from blood by 16.4% and by an unknown route by 1.7%. Intravenous drug use was reported by 29%; it was the most important risk factor for HIV transmission. The alanine aminotransferase quotient (qALT was >1 for 40% of the patients, 93.6% had anti-hepatitis A virus antibody, 5.3% presented hepatitis B surface antigen, 44% were anti-hepatitis B core antigen positive and 53.8% were anti-hepatitis C virus (anti-HCV positive. The anti-HCV test showed a significant association with qALT>1. Patients for whom the probable HIV transmission route was blood had a 10.8 times greater risk of being anti-HCV positive than patients infected by other routes. Among 30 patients submitted to liver biopsy, 18 presented chronic hepatitis.

    Full Text Available 14.00 Normal 0 21 false false false ES-CO X-NONE X-NONE Lymphocytopenia and CD4+ T lymphocytopenia can be associated with many bacterial, fungal, parasite and viral infections. They can also be found in autoimmune and neoplastic diseases, common variable immu­nodeficiency syndrome, physical, psychological and traumatic stress, malnutrition and immunosuppressive therapy. Besides, they can also be brought into relation, without a known cause, with idiopathic CD4+ T lym­phocytopenia. Among viral infections, the Retrovirus, specially the human immunodeficiency virus, is the most frequently cause. However, many acute viral infections, including cytomegalovirus and Epstein Barr virus can be associated with transient lymphocytopenia and CD4+ T lymphocytopenia. As is well known, transient lymphocytopenia and CD4+ T lymphocytopenia are temporary and overcome when the disease improves. Nonetheless, severe CD4+ T Lymphocytopenia associated with chronic infections by human herpes virus has not been reported. We describe 6 cases of human immunodeficiency virus negative patients, with chronic cytomegalovirus and Epstein Barr virus infections and profound lymphocytopenia with clinical symptoms of cellular immunodeficiency. These patients improved rapidly with ganciclovir or valganciclovir treatment. We claim here that it is important to consider the chronic human herpes virus infection in the differential diag­nosis of profoundly CD4+ T lymphocytopenia etiology, when human immunodeficiency virus is absent, in order to start effective treatment and to determine, in future studies, the impact of chronic human herpes virus infection in human beings’ health.
